Question

A stone of mass 0.25kg is whirled in a circle of radius 1.5m.What is the maximum speed with which the stone can be whirled around if the string can withstand tension of 600N?​

Answer 1

Answer:

Hey friend here is the answer.

When the stone is whirled in a circle, it has centrifugal force acting outwards the line joining the centre.

Tension act towards the centre of circular path away from the stone

For maximum speed, these two must balance each other.

mv^2/r = T

This v is the maximum speed.

v^2 = Tr/m

v^2 = 600*4*1.5=600*6 = 3600

Thus v = 60m/s

Hence the maximum speed is 60m/s.
