On an equipotential surface :
- A work done by the electric field in moving a charge is positive
- B the electric field is perpendicular to the surface
- C electric field is tangential to the surface
- D work done by the electric field in moving a charge is negative
Answer & Solution
Correct Answer
(B) the electric field is perpendicular to the surface
Step-by-step Solution
Detailed explanation
On an equipotential surface, the electric potential is constant at every point, meaning the potential difference ( \(\Delta V\) ) is zero. Since work done is \(W=q \Delta V\), moving a charge along the surface requires zero work. For the work done by the electric field to be…
