Question

A ball of mass 2 kg is tied to the end of the string of 2 metre long and reward in a horizontal circle if the breaking tension of the string is 400 newton calculate the maximum velocity of the body

Answer 1

Answer:

Mass of stone(m) = 2Kg,

radius(r) = length of rope =2m,

Maximum tension of the string = maximum centripetal force experienced by the stone

=> mv2/r = 25

=> 2v2/3 = 25

=> 2v2 = 75

=> v2 = 37.5

=> v = 6.123 m/s
