Electrostatic Potential and Capacitance - Result Question 3
3. The diagrams below show regions of equipotentials. (a)
(b)
(c)
(d)
A positive charge is moved from $A$ to $B$ in each diagram.
(a) In all the four cases the work done is the same
(b) Minimum work is required to move $q$ in figure (a)
(c) Maximum work is required to move $q$ in figure (b)
(d) Maximum work is required to move $q$ in figure (c)
Show Answer
Answer:
Correct Answer: 3. (a)
Solution:
- (a) As the regions are of equipotentials, so Work done $W=q \Delta V$
$\Delta V$ is same in all the cases hence work - done will also be same in all the cases.
