(i) Can two equi-potential surfaces intersect each other? Give reasons.

Question 1

(ii) Two charges -q and + q are located at points A(0, 0, - a) and B(0, 0, + a) respectively.

How much work is done in moving a test charge from point P(7, 0, 0) to Q (-3, 0, 0)?

Question 2

(i) No

Reason: At the point of intersection, there will be two different directions of electric field, which is not possible.

(ii) Work done in moving test charge atom P to Q is zero.

Reason: Test charge is moved along the equatorial line of an electric dipole. As potential at every point on equatorial line is zero, so work done,
