Question

A stone of mass $m$ is tied to a string of length $l$ and rotated in a circle with a constant speed $v,$ If string is released the stone flies

• A. Radially outwards
• B. Radially inwards
• C. Tangentially outwards
• D. With an acceleration $\frac{m{v}^2}{l}$

Answer 1

Answer: (C)

Tangentially outwards

After releasing the string, centripetal acceleration will become zero, due to which the direction of velocity cannot change now and stone flies tangentially outwards.
