Question

A ball of mass 'm' is rotated in a vertical circle with constant speed. The difference in tension at the top and bottom would be ?

Answer 1

Answer:

Explanation:

Tension will be comparatively less than the lower position

Answer 2

Answer: it would be 2mg

Explanation: the tension at the top is= mv^2\r+mg

the tension at bottom would be= mv^2\r -mg

so the difference would b=e( mv^2\r +mg) -(mv^2\r-mg)

so by some basic Arithmetic we would get

                        " 2mg"

thanks and have a great day!!
