Therefore, when the given point is on the equatorial axis, the electric potential is zero.
Why is equatorial line potential zero?
Actually the potential due to one charge of the dipole is just equal and opposite to that of due to other charge on any point on the equatorial line,therefore the potential of a dipole vanishes on any point on the equatorial line. the above is due to symmetry of the charges of dipole and their opposite character.
What is the electric potential in equatorial position of an electric dipole?
Answer: The electric potential in equatorial position of an electric dipole is zero.
What is the direction of electric field on axial point and Equatorial point due to a dipole?
Answer: THE DIRECTION OF ELECTRIC FIELD IS IN THE SAME DIRECTION AS DIPOLE DIRECTION (FROM NEGATIVE CHARGE TO POSITIVE CHARGE) IN AXIAL POINT BUT IN EQUATORIAL THERE IS A ANGLE DIFFERENCE OF 180° BETWEEN DIPOLE DIRECTION AND EQUATORIAL POINT DIRECTION (FROM POSITIVE CHARGE TO NEGATIVE CHARGE).
What is the angle between the direction of electric field at any axial point and Equatorial point due to an electric dipole?
On equatorial line, the direction of electric field is reversed to that of angle of axial line. Therefore, the angle between dipole moment and electric field is 180°.
What is the direction of electric field intensity at a point on the axial E equatorial line of an electric dipole?
The correct answer for this question is option (4) Perpendicular to the equilateral line and parallel to P. Explanation : In an electric dipole at an equilateral position , the electric field component is perpendicular to the dipole moment .
What is axial line and equatorial line?
Axial line is the line which is passing through the positive and negative charges and the point lies on that line is called the axial point. Equatorial line is the perpendicular line to the line passing through the positive and negative charges and the point lies on that line is known as the equatorial point.
What is angle between electric dipole moment and electric field due to it on equatorial line?
The angle between electric dipole moment and electric field on the equatorial line is 180° as both of them are in opposite directions.
What is the angle between the electric field and dipole moment of a dipole at a point on its I equatorial plane II Axis?
As, angle between the dipole moment and electric field at any point on the equatorial plane is 180∘.
What is the angle between dipole moment and electric field due to dipole on axial line?
the angle between electric dipole moment and electric field strength due to dipole on axial line is 180°.
How does an electric field of short electric dipole vary with distance on the equatorial line?
For an electric dipole (at large distances), The electric potential varies inversely with the square of the distance. For a point charge, The electric potential varies inversely with the distance.
What is the angle between the electric dipole moment p and the electric field strength E lohen the dipole is in a stable equilibrium?
The dipole is in constant equilibrium if θ = 00. A dipole in stable equilibrium, when Electric filed and dipole moment are perpendicular to each other i.e. the angle between them is zero degrees and torque will be maximum.
What is electric field due to dipole?
About. Two equal and opposite charges separated by some distance constitute a dipole. The electric field strength due to a dipole, far away, is always proportional to the dipole moment and inversely proportional to the cube of the distance.
What is the angle between the direction of electric field?
Answer: At AXIAL POINT the angle between direction of electric field and dipole moment is 0°.
When an electric dipole is held at an angle in uniform electric field the net force and torque?
Answer: the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the net force on the dipole is zero. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.
At what angle of electric dipole moment with uniform electric field potential energy is maximum?
When the angle between the dipole moment and electric field is 180° then the potential energy of electric dipole is maximum.
Which statement is wrong about lines of electric field?
Electric field lines does not forms closed loop as line can never start and end on the same charge.
When an electric dipole is held at an angle in a uniform electric field?
1) the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the net force on the dipole is zero. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.
What is the angle between electric field and equipotential surface?
The angle between the electric field and the equipotential surface is always 900. The equipotential surface is always perpendicular to the electric field.
Why is the angle between the electric field and equipotential surface always 90?
This is because the electric field is defined as the (negative) gradient of the electrostatic potential, which means that the only electric field is allowed at a point on an equipotential must be perpendicular to the equipotential surface, otherwise it would have a non-zero component along the surface.
Why are equipotential lines perpendicular to electric field lines?
Since the electric field lines point radially away from the charge, they are perpendicular to the equipotential lines. … The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines.
What will be the value of electric field at the Centre of electric dipole?
Answer: Twice the electric field.
What direction do electric field lines travel?
These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges.
