Question : 7

Total: 54

Six charges of equal magnitude but opposite sign are fixed on an insulating ring at equal separation. P is a general point on the axis of ring at large distance from the centre of ring. PR is a path perpendicular to the axis of the ring and R is at infinite separation from P.

Amount of work done to bring a charge from R to P via RP is zero.
Net dipole moment is zero and electric field is conservative field.
Amount of work done to bring a charge from R to P via RP is zero because net dipole moment is zero and electric field is conservative field.
Amount of work done to bring a charge from R to P via RP is zero not because of net dipole moment is zero and electric field is conservative field.
