A spherical conducting shell of inner radius `R_(1)` and outer radius `R_(2)` has charge Q. Now a charge q is placed inside the shell but not at centre then surface charge densities with their nature on inner and outer surfaces of shell are respectively.

A spherical conducting shell of inner radius r_1 and outer radius r_2 has a charge Q as shown in the figure. A charge q is placed at the centre of the shell. What is the surface charge density of the inner and outer sufaces of the shell?

A spherical conducting shell of inner radius r_(1) and outer radius r_(2) has a charge Q. (a) A charge q is placed at the centre of the shell. What is the surface charge density on the inner and outer surfaces of the shell? (b) Is the electric field inside a cavity (with no charge) zero, even if the shell is not spherical, but has any irregular shape? Explain.
