A negatively charged ebonite rod is made to touch an insulated brass sphere. The brass sphere gets electrically charged by the process of Induction/ conduction

When a negatively charged ebonite rod is brought near a negatively charged and freely suspended ball, then the ball :

A positively charged ball is brought close to a neutral conducting isolated sphere. The isolated sphere is grounded for an instant and then the ground connection is removed.Consider the followingstatements . STATEMENT-1 : The sphere will acquire a negative charge after this process. and STATEMENT-2 : If the sphere is kept grounded and positively charged ball is moved away, the sphere will again become neutral.

When a negatively charged ebonite rod is brought close to an uncharged electroscope, the leaves of the electroscope develop positive charge and diverge.

Two identical conduction spheres, one having an initial charge +Q and the other initially uncharged, are brought into contact. (a) What is the new charge on each sphere? (b) While the spheres are in contact, a positively chaged rod is moved close to one sphere, causing a redistribution of hte charges on the two spheres so the charge on hte sphere closest to the rod has a charge-Q. What is the charge to the other sphere?

The net charge given to an isolated conducting solid sphere :

Two spheres of radius a and b respectively are charged and joined by a wire. The ratio of electric field of the spheres is

Consider two concentric conducting spheres. The outer sphere is hollow and initially has a charge -7Q on it. The inner sphere is solid and has a charge +2Q on it. a. How much charge is on the outer surface and inner surface of the outer sphere. b. If a wire is connected between the inner and outer sphere, after electrostatic equilibrium is established how much total charge is on the outer sphere? How much charge is on the outer surface and inner surface of the outer sphere? Does the electric field at the surface of the inside sphere change when the wire is connected? c. We return to original condition in (a). We now connect the outer sphere to ground with a wire and then disconnect it. How much total charge will be on the outer sphere? How much charge will be on the inner surface and outer surface of the outer sphere?
