Chapter 6, Problem 1FC

To determine

The correct option.

Answer to Problem 1FC

The correct option is (e) C, A, B.

Explanation of Solution

Description:

The work done is defined as the product of force and displacement. The work done is positive, if both force and displacement are in the same direction.

In the case C, the force is perpendicular to the displacement. This shows that the force will have no impact on the object as the displacement and force are from two different ends. Therefore, there is no work done.

In the case A, the force applied is at an angle to the displacement and at the same time, it is in the direction of the displacement. Hence, the force is not at its maximum value, yet it is higher than zero. Therefore, the work done is between zero and the maximum.

In the case B, the force and displacement are in the same direction and this implies that the force will be at its peak when compared to other two cases. Thus, the work done is at the maximum in this case.

Thus, the ascending order of the work done is $\text{C}<\text{A}<\text{B}$.

Therefore, option e is correct, and the remaining options a, b, c, and d are incorrect.

Conclusion:

Thus, the correct option is (e) C, A, B.
