An electron is projected from a distance d and with initial velocity u parallel to a uniformly charged flat conducting plate as shown. It strikes the plate after travelling a distance ℓ along the direction of projection. The surface charge density of the conducting plate is equal to

one becomes positively charged while the other becomes negatively charged. Then Two bodies are changed by rubbing one against the other. During the process
