A particle of mass m and charge q is projected into a region having a uniform magnetic field B0. Initial velocity (v0) of the particle is perpendicular to the magnetic field. Apart from the magnetic force the particle faces a frictional force which has a magnitude of f = kv where v is instanta- neous speed and k is a positive constant.
(a) Find the radius of curvature of the path of the particle after it has travelled through a distance of `x_(0)=(mv_(0))/(2K).`
(b) Plot the variation of radius of curvature of the path of the particle with time (t).
