If the speed of the stone is increased beyond the maximum permissible value, and the string breaks suddenly, which of the following correctly describes the trajectory of the stone after the string breaks?
विकल्प
The stone moves radially outwards.
The stone flies off tangentially from the instant the string breaks.

उत्तर
The stone flies off tangentially from the instant the string breaks.
Explanation:
The trajectory of the stone after the string breaks, i.e., the stone flies off tangentially from the instant the string breaks.The velocity is always tangential to the circle at every point during the circular motion. When the string breaks, the particle proceeds to move in the tangential direction in accordance with Newton's first law of motion.
