Q. Let $V$ be the electric potential at a given point. Then the electric field $E_{x}$ along $x$-direction at that point is given by
A) $\int_{0}^{\infty}{V\ dx}$
B) $\frac{dV}{dx}$
C) $- \frac{dV}{dx}$
D) $- V\frac{dV}{dx}$
Explanation
(c) Relation between electric field and electric potential is given by, $E = - \frac{dV}{dx}$
