Question

167. The diagrams below show regions of equipotentials.

A positive charge is moved from A to B in each diagram.
(1) Maximum work is required to move q in figure (c).
(2) In all the four cases the work done is the same.
(3) Minimum work is required to move q in figure (a).
(4) Maximum work is required to move q in figure (b).

Answer 1

Answer:

what time do you want to do the question is how much you want to do something

Answer 2

Answer:

b ) In all four cases the work done is the same

Explanation:

W = (V2 - V1) q

from the eqtn of V,

V = W/q

here charge q is the same in all four cases.

V2 - V1 is also the same in all four cases.

hence all the work is the same.
