Questions
A stone tied to a string is rotated with a uniform speed in a vertical plane. If mass of the stone is m, length of the string is r and linear speed of the stone is v, then tension in the string when the stone is at its lower point is ( g = acceleration due to gravity)
detailed solution
Correct option is D
We know that centrifugal force =mv2/rWhen the stone is at the lowest point, the tension in string = centrifugal force + weight of stoneâ´ T=mv2r+mgTalk to our academic expert!
