A nonconducting ring of mass m and radius R is charged as shown The charged density i e charged per unit length is It is then placed on a rough nonconducting horizontal surface plane At time t 0 a uniform electric field E Ei is switched on and the ring start rolling without sliding Determine the friction force magnitude and direction acting on the ring when it start moving
