Solution
The correct option is D −50 nC,−100 nC
The charge +50 nC at the centre induces −50 nC on inner surface and +50 nC on outer surface of the spherical sheet.
So, charge on the inner surface =−50 nC
and charge on the outer surface =−150 nC+50 nC
=−100 nC.
The charge +50 nC at the centre induces −50 nC on inner surface and +50 nC on outer surface of the spherical sheet.
So, charge on the inner surface =−50 nC
and charge on the outer surface =−150 nC+50 nC
=−100 nC.
