A charged metallic sphere A having charge ` q_A` is brought in contact with an uncharged metallic sphere of same radius and then separated by a distance ` d`. What is the electrostatic force between them

A metallic sphere of radius R having charge Q is connected to an uncharged sphere of radius 3R . The amount of charge flown through connecting wire is

Two spheres are separately charged and then brought in contact, so

There are two uncharged identicasl metallic spheres 1 and 2 of radius r separated by a distance d(dgtgtr) . A charged metalllic sphere of same radius having charge q is touched with one of the sphere. After some time it is moved away fom the system. Now, the uncharged sphere is earthed. Charge on earthed sphere is

A charged metalllic sphere of same radius having charge q is touched with one of the sphere. After some time it is moved away fom the system. Now, the uncharged sphere is earthed. Charge on earthed sphere is

A large insulated sphere of radius r charged with Q units of electricity is placed in contact with a small insulated uncharged sphere of radius r' and is then separated. The charge on the smaller sphere will now be.
