Question

Two 25.0N weights are suspended at opposite ends of a rope that passes over a frictionless pulley. What is the tension in the rope?

Answer 1

Answer:

tension in rope = 25.0 N

Explanation:

• Two forces act on the suspended weight. The force coming down is the gravitational force and the upward force by the tension in the rope.

• Since the suspended weight is not accelerating so that the net force will be zero. Therefore the tension in the rope should be 25 N.

       ∑F = F - W = 0

       so

       F = W

       so tension in rope = F  = T  = 25 N
