Current Question (ID: 16505)

Question:

$\text{The diagrams below show regions of equipotentials.}$ $\text{A positive charge is moved from A to B in each diagram. Then:}$

Options:

1. $\text{the maximum work is required to move } q \text{ in figure (iii).}$
2. $\text{in all four cases, the work done is the same.}$
3. $\text{the minimum work is required to move } q \text{ in the figure (i).}$
4. $\text{the maximum work is required to move } q \text{ in figure (ii).}$

Solution:

$\text{We know that, Work done (W) = } q \Delta V$ $\Delta V \text{ is same in all the cases.}$ $\text{So, work done will be same in all the cases.}$
