At which angle is the work done maximum?
Correct answer: C. 0 degree
- A. 45 degrees
- B. 90 degrees
- C. 0 degree
- D. 180 degrees
Explanation
The work done is maximum when the angle between the force applied and the displacement is 0 degrees (parallel).Therefore, the correct answer is C) 0 degrees.When the angle between the force and displacement is 0 degrees, it means that the force is applied in the same direction as the displacement. In this case, the work done is given by the equation:Work = Force x Displacement x cos(0)Since the cosine of 0 degrees is 1, the work done is maximized. This occurs when the force and displacement are aligned, and the full magnitude of the force contributes to the work done.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
