Charges 
and 
are given to three concentric conducting spherical shells 
and 
respectively, as shown in the figure. The ratio of charges on the inner and the outer surfaces of the shell 
will be (+ve value indicates same ratio of charges)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The electric field inside a conductor is zero. So if we take a Gausian spherical surface inner surface of the shell C, the flux on it will be zero. Hence from Gauss's law, the charge on the inner surface of shell C should be conservation of charge, charge on the outer surface of 
will be +
