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:
the stone moves radially outwards,
the stone flies *** tangentially from the instant the string breaks,
the stone flies *** at an angle with the tangent whose magnitude depends on the speed of the particle?
The answer is 2. When a particle moves in a circular path, at each point the velocity is directed along the tangent of the circular path. Hence when string, breaks, it moves along the tangent in accordance with Newton’* 1st law of motion.
