A non-spherical hollow conductor is given a charge Q. What is the electric field in the cavity?

Inside a charged spherical shell, the electric field is zero.

A long charged cylinder of linear charged density lambda is surrounded by a hollow co-axial conducting cylinder. What is the electric field in the space between the two cylinders?

A spherical shell of radius R has a charge +Q units. The electric field due to the shell at a point

A spherical conducting shell of inner radius r_1 and outer radius r_2 has a charge Q: Is the electric field in a cavity (with no charge) zero even if the shell is not spherical, but has any irregular shape? Explain.

Two point charges q and -q is placed at a distance 2a apart.Calculate the electric field at a point P situated at a distance r along the perpendicular bisector of the line joining the charges. What is the electric field when r gtgt a ? Also, give the direction of electric field W.r.t. electric dipole moment? .

A spherical conducting shell of inner radius r_1 and outer radius r_2 has a charge Q as shown in the figure. Is the electric field isnide a cavity (with no charge) zero, even if the shell is not spherical, but has any irregular shape? Explain.

A hollow sphere of charge does not produce an electric field at any

Faraday cage: A Faraday cage or Faraday shield lies an enclosure made of a conducting material. The fields within a conductor cancel out with any external fields, so the electric field within the enclosure is zero. These Faraday cages act as big hollow conductors you can put things in to shield them from electrical fields.Any electrical shocks the cage receives, pass harmlessly around the outside of the cage. An isolated point charge +q is placed inside the Faraday cage. Its surface must have charge equal to

A spherical conductor of radius 12 cm has a charge of 1.6 xx 10^-7C distributed uniformly on its surface. What is the electric field inside the sphere?
