Question
A stone tied to a string is rotated with a uniform speed in a vertical plane. if mass of the stone m, the length of the string is rand the linear speed of the stone is v, when the stone is at its lowest point, then the tension in the string will be
(g = acceleration due to gravity)
(g = acceleration due to gravity)
Options
A.
+ mg
+ mgB. - mg
- mgC.
D.mg
Solution
At the lowest point, as shown the figure both mg and centrifugal force
will act in the same direction so, T = mg +
