STANDARD Physics Work and Energy MCQ Question
Type: MCQ-conceptual-Medium
The work done to move a unit charge along an equipotential surface from P to Q
A
must be defined as - ∫E·dl
B
is zero
C
can have a non-zero value
D
both (a) and (b) are correct.
Correct Answer
Option D
Detailed Explanation
Work done to move a unit charge along an equipotential surface is zero because the electric field is perpendicular to the path, making the integral of E·dl equal to zero.
