Answer 2

The correct answer is option (a) It acts towards the hand.

Explanation:

• A force that makes a body follow a curved path is referred as centripetal force.
• The centripetal force act on the stone acts towards the hand.
• When the student is swirling the stone with a sling, the stone is performing a horizontal circular motion.
• Now, the hand of the student is actually the centre upon which the circular trajectory is taking place.
• Hence, the centripetal force will be directed radially in words towards the hand of the girl.
