Question
If an object of mass 2 kg is falling from a height of 6 m, then find the potential energy of the object (g=10 m/s2).
- 100
- 150
- 120
- 160
Hint:
- P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (10 m / s2 at the surface of the earth) and h is the height in meters
The correct answer is: 120
- P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (10 m / s2 at the surface of the earth) and h is the height in meters
- P.E= 2.10.6=120 Joule
