If in the electric field of a point charge q, a test charge is carried from (I) A to B and (II) A to C:
(a) The work done in case I is greater that the work done in case II.
(b) The work done in case II is greater than the work done in case I.
(c) The work done in both the cases is same but not zero.
(d) The work done in both the cases is same and zero.
[B & C lie on spherical surface]
