Question

a string can sustain a maximum force of 100N without breaking. a mass of 1kg is tied to one end of the piece of string of 1m long and it is rotated in a horizontal plane. compute the maximum speed with which the body can be rotated without breaking the string

Answer 1

The maximum speed with which the body can be rotated without breaking the string is Speed = N/1kg

Explanation:

As we known that:

Force = mass(weight) × acceleration (a)

Here acceleration will be taken as speed.

Force = mass(weight) × Speed

Given data:

Force = N   ( S.I unit of force)

Mass = 1 kg ( Kg is S.I unit of mass of an object)

Speed = Force / mass

Speed = N/1kg

Thus the maximum speed with which the body can be rotated without breaking the string is Speed = N/1kg
