Question

a) What are the forces acting on the block when it is hanging freely from the spring scale?b) What is the net force on the block? c) What are the magnitudes of each of the forces acting on the block? Explain.

Answer 1

a) Tension force y weight

b) 0 N

c)

Weight = 57.2N

Tension = -57.2 N

Explanation:

a) We have a block hanging freely, this means that there are two forces acting on it: the tension force of the spring and the force of gravity on the block itself (weight).

b) The net force is zero since the block is not accelerating.

c) The magnitudes of the tension and that of the weight are the same but in opposite directions, that is, with different signs, the weight is marked as 57.2 N and the tension would then be -57.2 N.
