Question

Electric potential at the centre of a charged hollow metal sphere is

• A. zero
• B. twice as that on the surface
• C. half of that on the surface
• D. same as that on the surface

Answer 1

Answer: (D)

Electric potential of charged spherical shell
$V=\frac{q}{4\pi {\epsilon }_{0}R}[0\le r\le R]$
$\therefore$ Electric potential at centre $=$ Electric potential on the surface
