A stone of mass 1000 g tied to a light string of length 10/3 m is whirling in a vertical circle. If the ratio of the maximum tension to minimum tension is 4 and g = 10 ms -2 , then speed of stone at the highest point of circle is
Text Solution
Verified by ExpertsThe correct answer is:
D
T max = 
and T min = 
Then 
= 
…………. (i)
Using v 2 – u 2 = 2aS, we get
v h 2 - v l 2 = - 2g(2L) = -4gL
or v l 2 = v h 2 + 4gL
Then from (i) 
or
4 = 
or 3v h 2 = 300 = or v h = 10 ms -1
