**A mass on a spring A oscillates at twice the frequency of the same mass on spring B. Which statement is correct?**

A. The spring constant for B is one quarter of the spring constant for A.

B. The spring constant for B is 4 times the spring constant for A.

C. The spring constant for B is half of the spring constant for A.

D. The spring constant for B is 1.41 times the spring constant for A.

E. The spring constant for B is twice the spring constant for A.

**Answer:**

the frequency is proportional to the √ of the spring constant
