Question

13. Two uniformly charged non-conducting hemispherical shells each having uniform charge density o
and radius R from a complete sphere (not stuck together) and surround a concentric spherical
conducting shell of radius
R
2
If hemispherical parts are in equilibrium then minimum surface charge
density of inner conducting shell is
(1) -20
(2)
Nia
(3) -0.
(4) 20​

Answer 1

Answer:

The question is not clear. Although I'll give you an idea

Explanation:

It will be the double of the charge density on onr shell. As to neutralise it, an opposite charge develops on thr inner shell.
