+ ve
- ve
maximum
zero

Solution Explained:

To solve this problem, we apply the core principles of Work Done by Constant and Variable Forces. Understanding the underlying formula is key to arriving at the correct answer below:

As Angle between tension force and displacement is 90°. Work done is zero

4. A uniform force of \(F = (3\hat{i} + \hat{j})\text{ N})\) acts on a particle of mass \(2\text{ kg})\). Hence the particle is displaced from position \(\vec{r_1} = (2\hat{i} + \hat{k})\text{ m})\) to position \(\vec{r_2} = (4\hat{i} + 3\hat{j} - \hat{k})\text{ m})\). The work done by the force on the particle is: (2013)
5. 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.
