Question

A rope of mass 5 kg is moving vertically in vertical position with an upwards force of 100 n acting at the upper end and a downwards force of 70 n acting at the lower end. The tension at midpoint of the rope is

Answer 1

tension in the rope is uniformly distributed so tension at any point on the rope will be the same. an upward force of 100  Newton and a downward force of 70 newton is acting so the difference in the force will be the tension which is equal to 30 Newtons
