Question

A stone of mass 1 Kg tied to a light inextensible string of length L = 10/3 m is whirling in a circular path of radius L in vertical plane.
If the ratio of the maximum tension to the minimum tension in the string is 4. What is the speed of stone at the highest point of the circle..?? ( Taking g = 10 m

Answer 1

mass =1 kg

length i.e radius =10/3 m

g =10 m/s^2

velocity at top position =

$\sqrt{rg \: }$

Answer =5.77 or 10 ÷ 1.732

Answer 2

Answer:
