Considering a group of positive charges, which of the following statements is correct? (a) Net potential of the system cannot be zero at a point but net electric field can be zero at that point (b) Net potential of the system at a point can be zero but net electric field can't be zero at that point. (c) Both the net potential and the net electric field cannot be zero at a point. (d) Both the net potential and the net field can be zero at a point.

Answer: (a). Each positive charge gives V = kq/r > 0, so the sum of potentials can never be zero. Fields are vectors and can cancel, e.g. midway between two equal positive charges E = 0. So the answer is (a).

Considering a group of positive charges, which of the following statements is correct?

Show answer and solution

Answer: (a)

Each positive charge gives $V = \frac{kq}{r} > 0$ , so the sum of potentials can never be zero.
Fields are vectors and can cancel, e.g. midway between two equal positive charges $E = 0$ .
So the answer is (a).
