Question

Calculate acceleration of system, tension in string for the following diagram.
60º|5kg
20kg
30°​

Answer 1

Answer:

For the system to be in equilibrium, T = Fg. The net force is 2Fg - 2T = 0, so there is no acceleration. The tension in the string is 2T or 2Fg. The string supports both masses, so we would expect the tension in this case to be the sum of the two downward forces.
