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)

same as that on the surface

Answer 2

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