Question
A stone of mass of 16 kg is attached to a string 144 m long and is whirled in a horizontal smooth surface. The maximum tension the string can withstand is 16 N. The maximum speed of revolution of the stone without breaking it, will be :
Options
A.20 ms-1
B.16 ms-1
C.14 ms-1
D.12 ms-1
Solution
r = 144 m, m = 16 kg, Tmax = 16 N
T =
v =
= 
= 10 m/s Ans.
T =
v =
