the maximum tension that an inextensible ring of mass density 0.1 kg/m can bear is 40 N.the maximum velocity with which it can be rotated in a circular path?
Let ‘r’ be the radius of the ring.
Mass per unit length of the ring is, ρ = 0.1 kg/m
Let the maximum linear speed of rotation be ‘v’.
So, mv2/r = 40
=> (2πr X ρ)(v2)/r = 40
=> 2πρv2 = 40
=> (2)(3.14)(0.1)v2 = 40
=> v2 = 63.69
=> v = 7.9 m/s
