A hollow insulated conduction sphere is given a positive charge of $10 \mu \mathrm{C}$. What will be the electric field at the centre of the sphere if its radius is $2 \mathrm{~m} ?$
Zero
$5 \mu \mathrm{Cm}^{-2}$
$20 \mu \mathrm{Cm}^{-2}$
$8 \mu \mathrm{Cm}^{-2}$
Solution
Electric field at centre of narrow sphere is always zero..
