To solve the problem of rolling pendulum angular acceleration, it's essential to demonstrate an attempt at a solution. Participants are encouraged to reference specific methods taught in their module related to the topic. Sharing any preliminary work or calculations is crucial for receiving targeted assistance. Clarifying any remaining questions will help facilitate a better understanding of the concepts involved. Engaging actively in the problem-solving process is key to mastering the subject.
The answer is (B) but I don't really understand why.
Based on formula of Young Modulus:
$$x=\frac{FL}{AE}$$
The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A##
I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
