Maurice pulls on the end of a spring scale. He lets go of the end and observes the spring snap back into place. What force restores the spring to its original shape?

a. tension

b. elastic

c. drag

d. applied

Respuesta :

Elastic is the right answer.

Answer:

Elastic Force

Explanation:

As we pull the spring from one of its end by some distance such that its length is stretched by some amount "x"

So here the restoring force on the spring is given as

[tex]F = kx[/tex]

so here we know

k = coefficient of elasticity

x = change in the length of spring

So here the restoring force on the spring will be Elastic force which always act opposite to the direction of displacement of the spring
