Question

Intensity of electric field inside a uniformly charged conducting hollow sphere is :

• A. zero
• B. non zero constant
• C. change with $r$
• D. inversely proportional to $r$

Answer 1

The correct option is A zero

Shell theorem:

Intensity of electric field inside a uniformly charged hollow sphere is zero and outside the sphere we can assume the sphere to be a point charge present at centre and calculate E.
$\therefore$ The voltage is also constant inside hollow sphere as $E=0$
