Electrostatics
Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then,
When a body is charged by induction, then the body
The part of the body nearer to the source charge gets induced charges, opposite in nature to the source charge while the other part gets those of similar nature.Thus no loss of charge.
Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then,
A sure test of electrification is:
In induction, a positively charged body can make an uncharged body positively charged.
Charging a conductor by bringing another charged conductor close to it without touching is called
Describe the method of charging a conductor by induction.
In induction the charge induced in the near surface of a dielectric is:
A piece of paper appears to be attracted to a charged ebonite rod, even before they touch (see fig.). The charge at A is :
