NEET Physics Question - Work Energy and Power - Work Done by Constant and Variable Forces

Assertion (A): Net work done by all the internal force of a system is independent of choice of reference frame.

Reason (R): Value of force is independent of choice of reference frame.

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

Work done by internal forces depends on relative displacement (\(\Delta \vec{r}\)) which is frame-independent, so (A) is true.

The value of a force is generally not independent of the reference frame, especially if non-inertial frames are considered, so (R) is false.
