A nonconducting ring of mass m and radius R, with charge per unit length λ is shown in fig. It is then placed on a rough nonconducting horizontal plane. At time t=0, a uniform electric field E→=E0iˆ is switched on and the ring starts rolling without sliding. Determine the friction force (magnitude and direction ) acting on the ring.
