Charge \(2q, - q\) and \( - q\) lie at the vertices of an equilateral triangle. The value of \(E\) and \(V\) at the centroid of the triangle will be
1 \(E = 0,\;V = 0\)
2 \(E = 0\;and\;V \ne 0\)
3 \(E \ne 0\;and\;V = 0\)
4 \(E \ne 0\;and\;V \ne 0\)
Explanation:
From the given diagram the net potential must be zero. Where as the net electric field at point 0 is non zero.

There is a uniform electric field of intensity \(A\) which is as shown. How many labelled points have the same electric potential as the fully shaded point?
1 \(2\)
2 \(3\)
3 \(8\)
4 \(11\)
Explanation:
As the electric field is uniform, for any given point, all points located on a plane perpendicular to the field at that point are at same potential. Hence three other points located on a line perpendicular to \(E\), drawn at the given (shaded) point, have same potential as the indicated point
