Which of the following statements are correct?

A. Electric field lines are always perpendicular to equipotential lines.
B. A zero electric field inside a conducting sphere does not mean that the potential gradient is also zero
C. The resultant of two electric fields is determined by vector addition of the two field strengths
D. If the field lines get closer together at any place, it means that the field strength is decreasing
E. The resultant potential at a point is just the sum of the individual potentials.

Choose the correct answer from the options given below:

A, C and E only

The correct answer is Option (1) → A, C and E only

(A) The electric field is always 1 to equipotential surface. This is because no work is done by the electric field when moving along an equipotential surface.

(C) The electric fields are vector quantities, so their resultant is found by adding the electric field vectors. This involve both magnitude and direction.

(E) The electric potential is a scalar quantity, so the potential due to multiple sources is the algebraic sum of individual potentials.
