Work done in moving a test charge q between two points along ANY path in an electrostatic field depends on
AThe speed of motion
BThe time taken
CThe path taken
DOnly the initial and final positions
Answer & Solution
Correct answer: D. Only the initial and final positions
The electrostatic force is conservative — work is path-independent and depends only on the initial and final positions. This is what makes the scalar potential V well-defined.
