A stone is tied to a string of length $$l$$ and is whirled in a vertical circle with the other end of the string as the centre. At a certain instant of time, the stone is at its lowest position and has a speed u. The magnitude of the change in velocity as it reaches a position where the string is horizontal (g being acceleration due to gravity) is

$$\sqrt {2\left( {{\mu ^2} - gl} \right)} $$

$$\sqrt {{u^2} - gl} $$

$$u - \sqrt {{u^2} - 2gl} $$

$$\sqrt {2gl} $$

A thin circular ring of mass M and radius r is rotating about its axis with a constant angular velocity $$\omega $$. Four objects each of mass m, are kept gently to the opposite ends of two perpendicular diameters of the ring. The angular velocity of the ring will be :

$${{M\omega } \over {4m}}$$

$${{M\omega } \over {M + 4m}}$$

$${{\left( {M + 4m} \right)\omega } \over M}$$

$${{\left( {M - 4m} \right)\omega } \over {M + 4m}}$$
