प्रश्न

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

विकल्प

  • will continue to move in the circular path

  • will move along a straight line towards the centre of the circular path

  • will move along a straight line tangential to the circular path

  • will move along a straight line perpendicular to the circular path away from the boy

MCQ

उत्तर

will move along a straight line tangential to the circular path

Explanation:

If the string breaks, the force that was causing it to move along a circular path, i.e., centripetal force is no longer there, so the stone will move along a straight line tangential to the circular path.
