A spherical gas cloud of radius Rhas total charge Q distributed uniformly in its volume A charged particle having charge q and mass mis projected from its centre with speed v Assume that the cloud doesn t exert gravitational force or any resistive force on the particle The minimum value of v so that the particle is able to escape the cloud is nQq where nis 4 mR
