Question

A boy is rotating a stone tied with a rope in horizontal circle of radius 0.5 m. The mass of stone is 2 kg and tangential velocity of stone is 2 m/s. Calculate the tension in the rope.

Solution: The tension in the rope, T will be equal to centripetal force (Fc).

==>T = mV^2/R

[where, m = mass, v = velocity, R = radius]

==>T = 2*2^2/0.5

==>T = 16 N (ANSWER)
