A 100 kg crate is attached to a rope wrapped around the inner disk as shown. A person pulls on another rope wrapped around the outer disk with force F to lift the crate.
What force F is needed to lift the crate 2 m?
1.about 20 N
2.about 50 N
3.about 100 N
4.about 200 N
5.about 500 N
6.about 1,000 N
7.about 2,000 N
8.about 5,000 N
9.Impossible to determine without knowing the radii
10.Impossible to determine for some other reason(s)
