Question

There are four springs stretched by the same mass. Spring A stretches 25 cm. Spring B stretches 10 cm. Spring C stretches 100 cm. Spring D stretches 1 cm.

Which spring has the largest spring constant?

A

B

C

D

Answer 1

Answer:D

Explanation:

I took the test on K12

Answer 2

Answer: D (1cm)

Explanation:

Force constant (k) = Fs/ x

k = force constant

Fs = spring force

x = compression

Increase in the length of the spring leads to decrease in the force constant.

Note : the length of the spring was converted from cm-metre.
