The electric force of repulsion on a tiny charged conducting sphere A as a function of its separation form a large conducting sphere B. The sphere B has 10 times the charge on the sphere A. Explain the behaviour of the force between separation 2 cm and 1 cm.

Two charged conducting spheres of radill a and b are connected to eachother by a wire. What is the ratio of electric fields at the surface of two spheres ? Use the result obtained to explain why charge density on the sharp and pointed ends of a conducter is higher than on its fatter portions ?

A drop of water of mass m falls away from the bottom of charged conducting sphere of radius R, carrying with it a charge q_(1) and leaving the sphere a uniformly distributed charge q_(2) . The kinetic energy of the drop after it has fallen height h is -
