A uniform disc of radius 20 cm and mass 2kg is fixed at its centre and can rotate about an axis through the centre and perpendicular to its plane. A massless cord is round along the rim of the disc. If a uniform force 2 newton is applied on the cord, tangential acceleration of a point on the rim of the disc will be:
detailed solution
Correct option is B
From τ=Iα, where I=MR2(2) (0.2)=2(0.2)22α⇒α=10rad/s2Linear acceleration = =αR=(10)(0.2)=2m/s2Talk to our academic expert!
