72kg is hanging on a rope .what is the force of tension on the rope ?

705.6 N

Explanation:

The object is hanging on the rope, so there are two forces acting on the object:

- The force of gravity, downward, equal to

W = mg

where m is the mass of the object and g the acceleration of gravity

- The tension in the rope, T, upward

Since the object is hanging motionless, the object is in equilibrium, so we can write:

And therefore

For this problem,

m = 72 kg

Substituting,
