Passage / Comprehension

A ring of mass m and radius R is rolling with constant velocity v on a horizontal surface. Young's modulus of material of ring is y and crosssectional area of the wire by which ring is made is A.

Tensile force applied by one half of the ring on the other half, due to its motion is :-

Options:

Answer:

Solution:

$2 T = \frac{m}{2} (\frac{2 R}{π}) ω^{2} 2 T = \frac{mR}{π} (\frac{v}{R})^{2} = \frac{mv ^{2}}{R π}$
