Question:
A pulley is massless and frictionless. A massless inextensible string is attached to these masses: m3 = m, m2 = m, and m1 = 4 m.
What is the tension T3 in the string connecting the two objects of equal mass? Answer in the format T3=(?)mg.
What is the magnitude of the net force on mass m3 where m1 > m3 + m2 , m3 > m2, and a is the magnitude of the acceleration of
the masses. Pick one below:
1. Fnet = (m3) a
2. Fnet = (m3-m2) a
3. Fnet = (m3-m2)g
4. Fnet = (m2) g
5. Fnet = (m2) a
6. Fnet = (m1-m3)g
7. Fnet = (m1) g
8. Fnet = (m1-m3) a
9. Fnet = (m3) g
10. Fnet = (m1) a
