Answer: Option 1: 1 J
Explanation:
Average mass of an apple is between 60 g to 200 g It is not greater than this.
We can take an average mass, m =130 g
This average mass approximation would not affect the final answer.
The work done in lifting any object is given by:
W = m g h
Where, m is the mass of the object, g is the acceleration due to gravity and h is the height to which the object is lifted.
It is given that, h = 1 m
g = 9.8 m/s²
m = 130 g = 0.13 kg
⇒W =0.13 kg×9.8 m/s²×1 m = 1.3 J ≈ 1 J
Thus, the work done in lifting an apple one meter near Earth’s surface is approximately 1 J
