The magnitude of electric field $\vec{E}$ in the annular region of a charged cylindrical capacitor : |
is same throughout is higher near the outer cylinder than near the inner cylinder varies as $\frac{l}{r}$ where $r$ is the distance from the axis varies as $\frac{l}{r^2}$ where $r$ is the distance from the axis |
varies as $\frac{l}{r}$ where $r$ is the distance from the axis |
The magnitude of electric field at a distance r from the axis is given as :
$E=\frac{\lambda}{2 \pi \varepsilon_0 r}$ i.e., $E \propto \frac{1}{r}$ Here, $\lambda$ is the charge per unit length of the capacitor. |
