An extended object comprises two point masses m₁ and m₂ connected via a rigid massless rod of length L.The object is rotating at a constant angular velocity about an axis perpendicular to the page through the midpoint along the rod.Two time varying tangential forces F₁ and F₂ are applied to m₁ and m₂ respectively as shown in the figure.After the shown forces have been applied,the angular velocity of the object A)increases. B)decreases. C)remains unchanged. D)There is not enough information to make a determination.

Question

Quizplus · Accepted Answer

Since the forces are tangential, they do not apply a torque about the axis of rotation. Therefore, the angular velocity remains unchanged.
