CBSE Class 12-science Answered
A spherical conducting sphere of inner radius R1 and outer radius R2 has a charge Q.A charge q is placed at the centre of the shell.What is the surface charged density on the(1)inner surface
(2)outer surface of the shell?
What is the expression for the electric field at a point to x>R2 from the centre of the shell?

Expert Answer
The total charge enclosed for the inner sphere is 'q'.
Hence, the surface charge density for the inner sphere is
The total charge enclosed for the outer sphere is 'Q+q'.
Hence, the surface charge density for the outer sphere is
The electric field at a point at a distance x from the sphere is given by Gauss' law
by imagining a sphere of radius x.
