Chapter 5, Problem 64P

GO Figure 5-56 shows a box of mass m₂ = 1.0 kg on a frictionless plane inclined at angle θ = 30°. It is connected by a cord of negligible mass to a box of mass m₁ = 3.0 kg on a horizontal fric tionless surface. The pulley is frictionless and massless. (a) If the magnitude of horizontal force $\stackrel{\to }{F}$ is 2.3 N, what is the tension in the connecting cord? (b) What is the largest value the magnitude of $\stackrel{\to }{F}$ may have without the cord becoming slack?
