A dielectric disc of radius R and uniform positive surface charge density sigma is placed on the grup with its axis vertical. A particle of mass m and positive charge q is dropped, along the axis of the disc from a height H with dropped, along the axis of the disc from a height H with zero intial velocity. The charge -mass ratio of the particle is (q)/(m)=(4epsion_(0)g)/(sigma). (i). Find the value of H if the particle just reaches the disc. (ii). Sketch the potential energy of the particle as a function of its height and find its height in equilibrium position. |
