The electric field due to a uniformly charged sphere of radius R as a function of the distance from its centre is represented graphically by
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
$E_{\text{inside}} = \frac{\rho}{3 \varepsilon_0} r$ (r < R)
$E_{\text{outside}} = \frac{\rho R^{3}}{3 \varepsilon_{0} r^{2}}$ $(r \geq R)$
i.e. inside the uniformly charged sphere field varies linearly $(E \propto r)$ with distance and outside varies according to $E \propto \frac{1}{r^2}$
