Question

When the string breaks, the stone will move in the direction of the velocity at that instant. According to the first law of motion, the direction of velocity vector is tangential to the path of the stone at that instant. Hence, the stone will fly off tangentially from the instant the string breaks?

Answer 1

Hey mate ..

the stone flies off tangentially from the instant the string breaks,

When the string breaks, the stone will move in the direction of the velocity at that instant. According to the first law of motion, the direction of velocity vector is tangential to the path of the stone at that instant. Hence, the stone will fly off tangentially from the instant the string breaks.

Answer 2

Yes, since the velocity vector is perpendicular to the position vector, as soon as the centripetal force gets zero, stone will follow the direction of velocity which is tangential to the position vector.
