Electric Field & Field Lines
(This question contains Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best describes the two statements.)
Statement-1: For a charged particle moving from point to point , the net work done by an electrostatic field on the particle is independent of the path connecting point to point Statement-2: The net work done by a conservative force on an object moving along a closed loop is zero.
Show answer and solution
Answer: (a)
- Statement-2 is true: a conservative force does zero net work around a closed loop.
- The electrostatic force is conservative, so the work from to is the same along any path; Statement-1 is true.
- Path independence follows directly from zero work over a closed loop, so Statement-2 explains Statement-1.
- So the answer is (a).
