Initial data: k (value of spring stiffness) = 100 N / m; Δl (spring extension) = 2 m.
The force of elasticity that will act on the spring during uniform stretching can be determined by Hooke’s law: Fel = k * Δl.
Let’s calculate the elastic force: Fel = 100 * 2 = 200 N.
Answer: An elastic force of 200 N. acts on the spring.
