Problem

A stone of mass

0.2 \text{ kg}

is tied to one end of a thread of length

0.1 \text{ m}

whirled in a vertical circle. When the stone is at the lowest point of circle, tension in thread is

52 \text{ N}

, then velocity of the stone will be :- (1)

4 \text{ m/s}

(2)

5 \text{ m/s}

(3)

6 \text{ m/s}

(4)

7 \text{ m/s}
