Question

Consider a thin spherical shell of radius $R$ with its center at the origin, carrying uniform positive surface charge density. The variation of the magnitude of the electric field and the electric potential $V\left(r\right)$ with the distance $r$ from the centre, is best represented by which graph ?

• A.
  
• B.
  
• C.
  
• D.
  

Answer 1

Outside the charged spherical shell
$E=\frac{kq}{r^2}$
$V=\frac{kq}{r}$
Inside charged spherical cell $E\left(r\right)$ is zero and $V\left(r\right)$ is constant.
