Question
A stone tied to a string is rotated in a vertical plane. If mass of the stone is m, the length of the string is r and the linear speed of the stone is v when the stone is at its lowest point, then the tension in the string at the lowest point will be :
Options
A.
+ mg
+ mgB.− mg
− mgC.
D.mg
Solution
T − = (centripetal force at lowest point)
