A positive point charge Q is kept (as shown in the figure) inside a neutral conducting shell whose centre is at C. An external uniform electric field E is applied. Then :

A positive point charge is placed inside a spherical metallic shell. The electric field lines are represented by

A point charge q is kept at e distance x from the centre of a neutral metallic cube.

A point charge q is placed with in the cavity of an electrically neutral conducting shell whose outer surface has spherical shape. Then,

A block of mass m and positive charge q is placed on an insulated frictionless inclined plane as shown in the figure. A uniform electric field E is applied parallel to the inclined surface such that the block is at rest. Calculate the magnitude of the electric field E.

A spherical conducting shell of radius r_(0) carry a charge q_(0) . Then value of electric field inside it is :-

A positive point charge (+q) is kept in the vicinity of an uncharged conducting plate. Sketch electric field lines originating from the point on to the surface of the plate. Derive the expression for the electric field at the surface of a charged conductor.

A positive point charge (+q) is kept in the vicinity of an uncharged conducting plate. Sketch electric field lines originating from the point on to the surface of the plate. Derive the expression for the electric field at the surface of a charged conductor.
