Question
Find the height of the particle if the body has a potential energy of 8 J and a mass of 1 kg.
- 0.8 m
- 0.9 m
- 0.3 m
- 0.5 m
Hint:
Potential energy= mass x gravitational acceleration x height.
The correct answer is: 0.8 m
Given,
Potential energy of the object = 8 J
mass of the object is falling = 1 kg
According to the formula,
Potential energy= mass x gravitational acceleration x height.
height = ( gravitational acceleration = 9.8m/s2)
height =
height = 0.8 m
