A thin hollow cylinder is free to rotate about its geometrical axis. It has a mass of

8 \mathrm{~kg}

and a radius of 20

\mathrm{cm}

. A rope is wrapped around the cylinder. What force must be exerted along the rope to produce an angular acceleration of

3\, \mathrm{rad} / \mathrm{s}^2

View answer and explanation

Correct option: C

4.8 \mathrm{~N}

Option C (

4.8 \mathrm{~N}

) is correct because it is the force required to produce the given angular acceleration, calculated using the moment of inertia and torque.
