Question

find the Force required to revolution a body of mass 0.2kg along a circular path of radius 2.5ms . so as to make 100 revolution in one minute
​

Answer 1

Explanation:

Centripetal force acting on a body having angular velocity ω and radius of circle 'r' is

ω=

t

θ

=

31.4

10×2π

=2 rad/s

F=mv

2

/r=mrω
