Question

What is the value of spring constant if force of 200 N is acting on it and the spring is compressed by 2m?

(a) 100 kgs^-2

(b) 100 kgs^-1

(c) 100 kg^2s^2

(d) 100 Kgs

I got this question in class test.

My question is from Work Done by a Variable Force in division Work, Energy and Power of Physics – Class 11

Answer 1

The correct option is (a) 100 kgs^-2

Best explanation: Force on a elongated/compressed spring is given by F = k*x where k is spring constant and x is elongation/compression. So, 200 = k*2 which gives k = 100 kgs^-2.
