Question

A ball of mass 0.12 kg is being whirled in a horizontal circle at the end of a string 0.5 m long. It is capable of making 231 revolutions in one minute. Find the breaking tension of the string

Answer 1

Answer:

35.110

Explanation:

Since its given that it is capable of making 231rpm

Therefore

• Tension = T(N)
• Mass = M (kg)
• Radius = R(meter)
• Angular velocity = W(rad/sec)

Formula :- T = M× R× W×W

W = 231 (rpm)

= 231 ÷ 60( rps)

= (231÷60) × 2 pie( rad per sec)

NOW SOLVE

T IS

M×R×W×W

0.12×0.5×7.7×7.7×pie×pie

35.110
