The outer shell is grounded and the inner one is given a charge +Q. A small particle having mass m and charge – q enters the outer shell through a small hole in it. The speed of the charge entering the shell was u and its initial line of motion was at a distance a=2–√R from the centre. (a) Find the radius of curvature of the path of the particle immediately after it enters the shell. (b) Find the speed with which the particle will hit the inner sphere. Assume that distribution of charge on the spheres do not change due to presence of the charge particle

a charge q is imparted to the inner shells. Now find the potential difference between the shells. Note that finally key K2 remains closed. key K1 is closed and opened and then key K2 is closed and opened. After the keys K1andK2 are alterbately closed n times each Two concentric shells of radii R and 2R are shown in (Fig. 3.115). Initially
