A circular ring of radius r made of a nonconducting material is placed with its axis parallel to a uniform electric field. The ring is rotated about a diameter through`180^0`. Does the flux of electric field change? If yes, does it decrease of increase?

A hemispherical body of radius R is placed in a uniform electric field E. If the field E is parallel to the base of the hemisphere the flux linked with it is

A hemispherical bowl of radius r is placed in uniform electric field E . The electric flux passing through the bowl is

A square frame of edge 10 cm is placed with its ositivae normal making on angle of 60^0 with a uniform electric field of 20 V m^(-1) . Find the flux of the electric field through the surface bounded by the frame.

A cyclinder of radius r and length l is placed in an uniform electric field in such a way that the axis of the cyclinder is parallel to the field. The flux of the field through the cyclindrical surface is

A circular conducting ring is rotated about one its diameter in a magnetic field

A ring of radius R , made of an insulating material carries a charge Q uniformly distributed on it. If the ring rotates about the axis passing through its centre and normal to plane of the ring with constant angular speed omega , then the magnitude moment of the ring is

A circular loop of diameter d is rotated in a uniform electric field until the position of maximum electric flux is found. The flux in this position is measured to be phi .What is the electric field strength?
