Answer 3

Suppose you have a charge Q at point A in a non-conservative electric field. You wish to move this charge to a point B present in that region. Now, if you moved Q from point A to B and back to A in a conservative electric field, the energy with which Q started from point A will be the same once Q returned to A from B. For example, in a conservative electric field, say Q started from A with 10 J of energy. Q then moves in that region, reaches B and moves back to A. When Q returns to A, the energy Q possesses is 10 J. So, in a conservative field, there is no loss or gain of energy when Q moves in a closed path. But this is not the case for a non-conservative electric field. Example for a conservative field is a static electric field( produced by charges at rest ). An example for a non-conservative field is a moving electric field( intensity at a point changes with time ) produced by moving charges.
