If force and displacement of particle in the direction of force are doubled. Work would be:
Correct answer: B. 4 times
- A. Double
- B. 4 times
- C. Half
- D. 1/4 times
Explanation
The work done by a force is given by the formula: Work = Force * Displacement If the force and displacement are doubled, then the work done will be 4 times the original work.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
