Question

The electric field due to a uniformly charged solid insulated sphere of radius R as a function of the distance from its centre is represented graphically by

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

For points inside a charged sphere,

$E\propto r$

And for points outside a charged sphere,

$E\propto \frac{1}{r^2}$
