AP Physics 1 rotational motion Question 7 Practice set MCQ

Answer 1

Let's find the torques for each force:

`\begin{gathered} \tau_1=d1\cdot F1=0.5\cdot200=100N\cdot m \\ \tau_2=d2\cdot F2=100\cdot1=100N\cdot m \\ \tau_3=d3\cdot F3=50\cdot1.5=75N\cdot m \\ \tau_4=d4\cdot F4=25\cdot2=50N\cdot m \end{gathered}`

Since the torque is directly proportional to the angular momentum. We can conclude that the answer is F4.
