Question

Hello people ~

If the outer shell is earthed, then the free charge on the outer surface goes to earth but the inner charge remains bounded to the charge on the inner shell so that the potential of the outer shell connected to the earth becomes ______________
a)6
b)2
c)0
d)8​

Answer 1

• c) 0

Step-by-step explanation:

• We know that charge on facing surfaces is equal and opposite
• So if charge on inner sphere is q₀, then charge on inner surface of shell should be −q₂ as the shell is earthed
• So its potential should be zero.
