Question 18 POST_UTME_OAU • 2022 • PHYSICS • objective

A point charge $q$ is placed at the origin of a coordinate system. If the electric potential $V$ at a point $P$ is given by the equation $V = \frac{k q}{r}$, where $k$ is Coulomb's cons\tant and $r$ is the dis\tance from the charge to point $P$, find the electric field $E$ at point $P$.

Correct Answer A. $ E = \frac{k q}{r^2} $

B. $ E = \frac{k q^2}{r} $

C. $ E = \frac{k q}{r^3} $

D. $ E = \frac{k q^2}{r^2} $

Correct Answer

Correct Option:

$ E = \frac{k q}{r^2} $
