Three Charges 29,- and - lie at vertices of a triangle. The value of E and V at centroid of triangle will be:

Options

A. `E ne0 and V ne0`
B. `E =0 and V=0`
C. `E ne 0 and V=0`
D. `E=0 and V ne 0`

Answer

C

Explanation

As can be seen from the diagram the net electric field is non-zero.
Potential at the centroid depends on the net charge which is zero and hence, potential is zero.
