Correct Answer - Option 2 : joule
CONCEPT:
- Work is a form of energy.
- It is the dot product of Force and Displacement.
\(W = \overrightarrow{F}.\overrightarrow{d}=Fd~cosθ\)
where W is the work done, F is the force, d is the displacement, and θ is the angle between F and d.
EXPLANATION:
- Since work is a form of energy.
- The unit of work will be the same as the unit of energy.
- So the SI unit of work is Joule.
- Hence the correct answer is option 2.
