A and B are two points at a separation of $$50$$ cm in a uniform electric field of $$24$$ $$V/m$$. If VA and VB are potentials at A and B respectively, the select the wrong option.

Question

A and B are two points at a separation of $$50$$ cm in a uniform electric field of $$24$$ $$V/m$$. If VA and VB are potentials at A and B respectively, the select the wrong option.

If A and B are on the same straight line and electric field lines are directed from A to B, then VA−$$VB=24$$×$$0.5$$ $$V=12V$$. If A and B are on the same straight line parallel to E→ and electric field lines are directed from B to A, then VA−$$VB=$$−$$24$$×$$0.5V=$$−$$12V$$. If A and B are on the same straight line which is perpendicular to E→, then A and B are on the same equipotential plane and VA−$$VB=0$$. So maximum potential difference between A and B is $$12$$ volt.Hence option (3) is correct.

A and B are two points at a separation of 50 cm in a uniform electric field of 24 V/m. If $V_{A}$ and $V_{B}$ are potentials at A and B respectively, the select the wrong option.
