Question

Three blocks, each having a mass of 1.06 kg, are connected by rigid rods of negligible mass and are supported by a frictionless surface. Forces F1 and F2, of magnitude 4.80 N and 10.1 N respectively, are applied to the ends of the blocks as shown in the figure below. Find the forces acting on block B (the +x direction is to the right).

The magnitude of the force applied by the rod on the left is (?) and is in the (+, , or no force) is applied x direction. The magnitude of the force applied by the rod on the right is (?) and is in the (+, , or no force) is applied x direction.

Explanation / Answer

All have equal masses.

The magntiude of the force applied by the rod on left is 4.8 N and it is -x direction.

The magntiude of the force applied by the rod on left is 10.1 N and it is +x direction
