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.
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.
