If in Q. 9 the speed of the stone is increased beyond the maximum permissible value, and the string breaks suddenly, which of the fallowing correctly describes the trajectory of the stone after the string breaks ?
(a) The stone jerks radially outwards.
(b) The stone flies off tangentially from the instant the string breaks.

Correctly describes the trajectory of the stone after the string breaks, i.e., the stone flies of tangentially from the instant the string breaks.
The velocity always acts tangentially to the circle at each point in the circular motion. At the time, the string breaks, the particle continues to move in the tangential direction according to Newton’s first law of motion.
