Question

A stone weighing 1 kg is whirled in a vertical circle attached at the end of a rope of length 0.5 m . Find the tension at

1)lowest position

Answer 1

Mg + Mv^2/r.

Gravitational force + centipital force

Answer 2

T1+ mg= (mv)2/r

T2- mg=(my) 2/r

T3-cos90=(my)2 /r

Solve it you will get tension at highest, mid& lowest point
