Read the following statements regarding equipotential surfaces: (A) For a uniform electric field, the equipotential surfaces are concentric spheres. (B) Two equipotential surfaces can never intersect each other. (C) The electric field is always tangential to the equipotential surface. (D) The work done in moving a test charge between any two points on an equipotential surface is zero. How many of the above statements

Options

  1. ATwo
  2. BOne
  3. CThree
  4. DFour

Correct answer

A. Two

Step-by-step solution

Statement (A) is incorrect because for a uniform electric field, the equipotential surfaces are parallel planes, not concentric spheres. Statement (B) is correct because if two equipotential surfaces intersect, there would be two different values of electric potential at the point of intersection, which is impossible. Statement (C) is incorrect because the electric field is always perpendicular (normal), not tangential, to the equipotential surface. Statement (D) is correct because the potential difference between
