Question

1. Electric field lines are drawn (a) from positive charges to negative charges (b) from negative charges to positive charges (c) from the largest charge to the smallest charge (d) from the smallest charge to the largest charge.

Answer 1

1. Electric field lines denotes the direction in which a positive charge would accelerate if kept on the line. Thus electric field lines are drawn away from the positive charge and towards the negative charge. thus correct answer is (a)

(a) Electric field lines are drawn from a positive charge to a negative charge.

2. The equipotentials are the points at which the potential is same. The measured eqquipotentials must be lines if the surface at which charge is present is flat.
