A ring rolls without slipping on the ground. Its centre C moves with a constant speed u. P is any point on the ring. The speed of P with respect to the ground is v.
- 0 < v < 2 u
- v = u, if CP is horizontal
- v = u, if CP makes an angle of 30° with the horizontal and P is below the horizontal levels of C
- \(v=\sqrt{2} u\), if CP is horizontal.
Answer
(A) 0 v 2 u, (C) v = u, if CP makes an angle of 30° with the horizontal and P is below the horizontal levels of C, (D) v= 2 u , if CP is horizontal.
