Vedclass · Answer

(A) For a stone tied to a string to complete a vertical circle,the minimum speed $v$ required at the lowest point is given by the formula $v = \sqrt{5gr}$,where $g$ is the acceleration due to gravity and $r$ is the length of the string.From the formula $v = \sqrt{5gr}$,it is clear that the speed $v$ depends only on the acceleration due to gravity $g$ and the radius (length of the string) $r$.It does not depend on the mass $m$ of the stone. Therefore,the minimum speed is independent of the mass of the stone.

$A$ stone tied to a string is rotated in a vertical circle. The minimum speed with which the string has to be rotated at the lowest point is:
