Electrostatics
Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then,
In induction, a positively charged body can make an uncharged body positively charged.
In induction, a positively charged body can make an uncharged body negatively charged because opposite charges will attract each other .
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
A sure test of electrification is:
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 :
