Question

Two springs of a spring constant 1508 of them and 3000 Newton per metre respectively are stressed with the same force they will have potential energy in the ratio

Answer 1

Potential energy = -F² / (2K)

For same force
Potential energy ∝ 1/K

Ratio of potential energies = K₂ : K₁
= 3000 N/m : 1508 N/m
≈ 2 : 1

Ratio of potential energy stored is nearly 2 : 1
