A disk with a rotational inertia of 5.0 kg.m² and a radius of 0.25 m rotates on a frictionless fixed axis perpendicular to the disk and through its center.A force of 8.0 N is applied along the rotation axis.The angular acceleration of the disk is: A)0 rad/s² B)0.40 rad/s² C)0.60 rad/s² D)1.0 rad/s² E)2.5 rad/s²

Question

Quizplus · Accepted Answer

The force applied does not produce a torque since it is applied along the rotation axis, meaning there is no angular acceleration.
