An uncharged sphere of metal is placed in a uniform electric field produced by two large conducting parallel plates having equal and opposite charges, then lines of force look like
Important Questions on Electrostatics
Two small conductors are given charges and , respectively. Now they are placed inside a hollow metallic conductor () carrying a charge Q. If all the three conductors are connected by conducting wires as shown, the charges on will be respectively
A positively charged body has been brought near a neutral brass sphere mounted on a glass stand as shown in the figure. The potential of will be:
The amount of work done by electric field in joules in carrying a charge along the closed path PQRSP between the oppositely charged metal plates is (where, is electric field between the plates)
Figure shows a closed surface which intersects a conducting sphere. If a positive charge is placed at the point P, the flux of the electric field through the closed surface:
An ellipsoidal cavity is carved within a perfect conductor. A positive charge is placed at the centre of the cavity. The points are on the cavity surface as shown in the figure.
The figure shows the current in a single-loop circuit with a battery and resistance (and wires of negligible resistance). Then find the order of following at the point and .
(a) The magnitude of the current,
(b) The electric potential, and
(c) The electric potential energy of the charge carriers (electron), the greatest first.
