Two blocks of masses 1 kg and 2 kg are joined by a massless inextensible string of length 3m. Both blocks are kept on a horizontal table as shown. Friction coefficient between 2 kg block and table is zero. They are rotated about a vertical axis passing at a distance of 1m from 1 kg. Force of friction on 1kg block is (assume that there is enough friction between 1 kg block ground)
