Question: If a spring extends by x on loading, then the energy stored by the spring is (if T is tension in the spring and k is spring constant)

[AIIMS 1997]

Options:

A) $ \frac{T^{2}}{2x} $

B) $ \frac{T^{2}}{2k} $

C) $ \frac{2x}{T^{2}} $

D) $ \frac{2T^{2}}{k} $

Show Answer

Answer:

Correct Answer: B

Solution:

$ U=\frac{F^{2}}{2K}=\frac{T^{2}}{2K} $
