A stone tied to a string of length L is whirled in a vertical circle with the other end of the string at 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 its velocity as it reaches a position where the string is horizontal is (a) √u² – 2gL 2 (c) √u² - gL (b) √2gL (d) √2(u²-gL) A stone tied to a string of length L is whirled in a vertical circle with the other end of the string at the centre.
