2A. Blocks A and B are connected by a cable that passes over a frictionless pulley as shown. If the weight of A is 100 N and the incline plane is smooth, (a) Draw the FBD of each block (b) what should be the mass of B to keep them at rest? (c) Find the magnitude and direction of the force exerted by the incline on the block. 30
