Question

When two springs A and B with force constants \(k_A\) and \(k_B\) are stretched by the same force, then the respective ratio of the work done on them is

• A. \(k_B : k_A\)
• B. \(k_A : k_B\)
• C. \(k_A k_B : 1\)
• D. \(\sqrt{k_B} : \sqrt{k_A}\)
• E. \(\sqrt{k_A} : \sqrt{k_B}\)

Hint:

For same force, softer spring (smaller \(k\)) stores more energy.

Answer 1

The Correct Option is A
