Two blocks rest on two frictionless ramps. They are connected at the apex of each ramp by a string and pulley. The angle of ramp A with the ground is 45 degrees. Mass of Block B (on Ramp B) is 2 times that of Block A. What does the angle of Ramp B with the ground have to be in order for the blocks to remain at equilibrium?
