Answer:

B: 50 N/m

Explanation:

Hopes it help.

The spring constant of the spring is 50 N/m. The correct option is B.

What is spring potential energy?

When the spring is compressed, it gets compressed up to its elastic limit. When load is removed from the spring, it regains its shape and obtains equilibrium position. The energy stored in this process is called as spring potential energy.

Given a spring has 100 J of EPE when it is stretched 2 m. The energy stored in the spring is given by

SPE = ½ kx²

100 = ½ k (2 m)²

k = 50 N/m

So, spring constant of the spring is 50 N/m.

Thus, the correct option is B.
