An annular ring with inner and outer radii R1 and R2 is rolling without slipping with a uniform angular speed. The ratio of the forces experienced by the two particles situated on the inner and outer parts of the ring, F1/F2 is

A body of mass m=10−2kg is moving in a medium and experiences a frictional force F=−KV^2. Its initial speed is υ0=10ms^−2. If after 10s its energy is 1/8mυ^2 0 the value of k will be
