MHT CET 2026 Physics question
Which of the following statements is NOT TRUE? a. Work done to move a charge on an equipotential surface is not zero. b. Equipotential surfaces are the surfaces where the potential is constant. c. Equipotential surfaces for a uniform electric field are parallel and equidistant from each other. d. Electric field is always perpendicular to an equipotential surface.
Solution
Check each statement. (a) The work done in moving a charge between two points is ; on an equipotential surface , so the work done is zero. Statement (a) says it is not zero, so it is NOT true. (b) An equipotential surface is by definition a surface of constant potential, so this is true.
