Solving the Forces on a Frictionless System

[CaptFormal]

Homework Statement

Three blocks on a frictionless surface are connected by massless strings, with M1 = 1.10 kg, M2 = 2.40 kg, and M3 = 3.60 kg. Due to the force F acting on M3, as shown, the system accelerates to the right. Given that T1 is 2.10 N, calculate T2

Label all the forces acting on all three of the blocks. Then do the usual net force equation. See where this gets you.
