Q.
Electric potential at the centre of a charged hollow metal sphere is
J & K CETJ & K CET 2007Electrostatic Potential and Capacitance
Solution:
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
