Question

A boy is whirling a stone tied with a string in a horizontal circular path. If the string breaks, the stone:

• A. will continue to move in the circular path
• B. will move along a straight line towards the centre of the circular path
• C. will move along a straight line tangential to the circular path
• D. will move along a straight line perpendicular to the circular path away from the boy

Answer 1

The correct option is C will move along a straight line tangential to the circular path

If the string breaks, the stone will move along a straight line tangential to the circular path because tension in the string is zero and the stone has tangential speed when the string breaks.
