Correct Answer - Option 3 :
10 J
CONCEPT:
-
Force: Force is defined as produce of mass times acceleration.
- SI unit of force is the Force (F).
Force = mass x acceleration
-
Work: Work is measured by the product of force and displacement of the body along the direction of the force.
- SI unit of work is Joule (J).
-
Energy: The capacity of doing work by a body is called its energy.
- SI unit of energy is Joule (J).
Calculation:
Displacement = 10 cm = 0.1 m
Force = 100 N
Energy or work = 100 × 0.1 = 10 J
