Question

In a hollow spherical shell, potential (V) changes with respect to distance (r) from centre as

• A.
  
• B.
  
• C.
  
• D.
  

Answer 1

The correct option is B


$\mathrm{For}r\le R\mathrm{Potential}\mathrm{inside}\left(V_{in}\right)=\frac{Q}{4{\mathrm{\pi \epsilon }}_{o}R}..\left(i\right)Forr\ge R\mathrm{Potentail}\mathrm{outside}\left(V_{out}\right)=\frac{Q}{4{\mathrm{\pi \epsilon }}_{o}r}..\left(ii\right)$
i.e. potential inside the hollow spherical shell is constant and outside varies according to $V\propto \frac{1}{r}$
