a stone tied to a string is whirled in a vertical circle with uniform speed. if the difference between the max and min tensions is 1kgwt, the mass of the stone is? (ans :0.5 k)
Please find below the solution to the asked query:
If a stone is tied to a string and whirled in a vertical circle, then,
When the stone is at its lowest point, tension in the string will be maximum as,
Where, m is the mass of the stone, v is the speed of the stone and l is the length of the stone.
When the stone is at its highest point, the tension in the string will be minimum as,
Given that the difference of maximum and minimum tensions is equal to . Therefore,
