A charge Q is uniformly distributed on a thin spherical shell. What is the field at the centre of the shell? If a point charge is brought close to the shell, will the field at the centre change? Does your answer depend on whether the shell is conducting or nonconducting?

A conducting sphere carrying charge Q is surrounded by a spherical conducting shell. a. What is the net charge on the inner surface of the shell? b. Another charge q is placed outside the shell. Now, what is the net charge on the inner surface of the shell? c. If q is moved to a position between the shell and the sphere, what is the net charge on the inner surface of the shell? d. Are your answer valid if the sphere and shell are not concentric?

A spherical shell made of plastic, contains a charge Q distributed uniformly over its surface. What is the electric field inside the shell? If the shell is hammered to deshape it without altering the charge. Will the field inside be changed? What happend if the shell is made of a metal?

An electric dipole is placed at the centre of a spherical shell. Find the electric field at an external point of the shell.

A spherical shell of radius R has a uniformly distributed charge ,then electric field varies as

The figure shows a spherical shell of mass M . The point A is not at the centre but away from the centre of the shell. If a particle of mass m is placed at A , then

Figure shows a uniformly charges hemispherical shell. The direction of electric field at point p that is off centre (but in the plane of the largest circle of the hemisphere), will be along

A uniformly charged non-conducting spherical shell is given +q charge and a point charge -q is placed as shown. The electric field lines will be

A point charge Q is placed inside a conducting spherical shell of inner radius 3R and outer radius 5R at a distance R from the centre of the shell. The electric potential at the centre of the shell will be
