Per NCERT Example 6.7, when a fruit falls from a tree, the Earth and fruit apply equal and OPPOSITE gravitational forces on each other. Why doesn't the Earth seem to move toward the fruit?
AThe fruit isn't really pulled by Earth
BThe Earth's mass is so enormous compared to the fruit's that the Earth's acceleration (a = F/m) is too tiny to observe
CEarth does move, just slowly each cycle
DNewton's Third Law fails here
Answer & Solution
Correct answer: B. The Earth's mass is so enormous compared to the fruit's that the Earth's acceleration (a = F/m) is too tiny to observe
Per NCERT Example 6.7, equal F but huge m_Earth gives negligible a_Earth. The other options are incorrect.
