NEET Physics Question - Work Energy and Power - Potential Energy & Equilibrium

Assertion (A): A spring has potential energy, both when it is compressed or elongated.

Reason (R): In compressing or stretching, work is done on the spring against the restoring force.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is true:

A spring stores elastic potential energy, calculated as \(U = \frac{1}{2}kx^2\), when it is compressed or stretched from its equilibrium position.

Reason (R) is true: This potential energy is stored because an external force does work against the spring's restoring force during deformation. Reason (R) correctly explains Assertion (A).
