Answer:
Restoring force of the spring is 50 N.
Explanation:
Given that,
Spring constant of the spring, k = 100 N/m
Stretching in the spring, x = 0.5 m
We need to find the restoring force of the spring. It can be calculated using Hooke's law as "the force on a spring varies directly with the distance that it is stretched".
[tex]F=kx[/tex]
[tex]F=100\ N/m\times 0.5\ m[/tex]
F = 50 N
So, the restoring force of the spring is 50 N. Hence, this is the required solution.
