Q2 of 46 Page 139

A metallic particle having no net charge is placed near a finite metal plate carrying a positive charge. The electric force on the particle will be

The metal plate carries a positive charge; it will induce an equal and opposite negative charge on the metallic particle following the law of electric induction. Hence, since electric field lines move from negative charge to positive charge, the force will pull the particle towards the plate.


Thus, option A is the correct option.

It is said that any charge given to a conductor comes to its surface. Should all the protons come to the surface? Should all the electrons come to the surface? Should all the free electrons come to the surface?

A charge Q is uniformly distributed over a large plastic plate. The electric field at a point P close to the centre of the plate is 10 V m–1. If the plastic plate is replaced by a copper plate of the same geometrical dimensions and carrying the same charge Q, the electric field at the point P will become

A thin, metallic spherical shell contains a charge Q on it. A point charge q is placed at the center of the shell, and another charge q1 is placed outside it as shown in the figure. All three charges are positive. The force on the charge at the centre is:

Consider the situation of the previous problem. The force on the central charge due to the shell is
