Q.
The magnitude of electric field $\overrightarrow{E}$ in the annual region of a charged cylindrical capacitor
A) Is same throughout
B) Is higher near the outer cylinder than near the inner cylinder
C) Varies as $\frac{1}{r^{\ },}$ where $r$ is the distance from the axis
D) Varies as $\frac{1}{{\ r}^{2},}$ where $r$ is the distance from the axis
Explanation
(c) $E \propto \frac{1}{r},\ where\ r\ is\ the\ distance\ from\ the\ axis.$
