A particle $P$ with mass $0.3\,\text{kg}$ is fixed to one end of a light inextensible string of length $0.6\,\text{m}$. The other end of the string is fastened to a fixed point $O$ on a smooth horizontal plane. $P$ travels on the plane at a constant speed of $5\,\text{m s}^{-1}$ in a circle centred at $O$.
