Question

Consider a thin spherical shell of radius $R$ with its centre at origin, carrying a uniform positive charge. The variation of electric field $\overrightarrow{E}\left(r\right)$ and electric potential $V\left(r\right)$ with radial distance $r$ from the centre is given by

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

As we know that inside a uniform spherical surface charge distribution, the electric field is zero and electric potential is constant.

$\overrightarrow{E}=0$ and $V=$ constant

At points outside the charge distribution

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

So, option $(c$) is correct.
