Question
The diagrams below show regions of equipotentials
A positive charge is moved from A to B in each diagram.
-
Maximum work is required to move q in figure (c).
-
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).
Solution
B.
In all the four cases the work done is the same.
Work was done w = qΔV
ΔV is same in all the cases so work is done will be same in all the cases.
