A long horizontal insulating cylinder of radius R and length L is free to rotate about its axis Curved surface of the cylinder carries charge Q which is uniformly distributed over it A string is wrapped around the cylinder at the end of which a point like mass m is hung The mass m start falling causing the cylinder to revoive about its axis Neglect moment of inertia of the cylinder 16 Torque on the cylinder due to electric field produced by charge on its surface is 4 Q Rg A H Q Rg L H Q Rg 4TL 1 H Q 47Lm B D L 1 H Q 4xLm H Q Rg 4TL
