Question

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 1

Answer: (A)

Net potential of the system cannot be zero at a point but net electric field can be zero at that point.

Answer 2

$V=\frac{\sum KQ_i}{r_i}$
Here , $Q_i$ and $r_i$ are positive
Therefore V > 0
So , the correct option is (A) : Net potential of the system cannot be zero at a point but net electric field can be zero at that point.
