    A solid cylinder is suspended symmetrically by two massless strings wound around it, as shown in the figure. The distance through which the cylinder should fall from its initial rest position, unwinding the strings, to achieve a speed of 4 ms−14{\text{ }ms}^{- 1} is ____\_\_\_\_ cm. (take g=10 ms−2g = 10{\text{ }ms}^{- 2} )

    A body of mass MM moving at speed V0V_{0} collides elastically with a mass ' mm ' at rest. After the collision, the two masses move at angles θ1\theta_{1} and θ2\theta_{2} with respect to the initial direction of motion of the body of mass MM. The largest possible value of the ratio M/mM/m, for which the angles θ1\theta_{1} and θ2\theta_{2} will be equal, is:
