The diagrams below show regions of equipotentials. [2017]
(a)
(b)
(c)
(d)
A positive charge is moved from A to B in each diagram.
-
- In all the four cases the work done is the same
- Minimum work is required to move q in figure (a)
- Maximum work is required to move q in figure (b)
- Maximum work is required to move q in figure (c)
Correct Option: A
As the regions are of equipotentials, so Work done W = q∆V
∆V is same in all the cases hence work - done will also be same in all the cases.
