Answer to Question #77785 in Classical Mechanics for Charvi

Question

Why dont two bodies come close when there is a gravitational force between them?
And in an atom two electrons of same or different orbital repel each atom why dont they go away

Answer 1

For example, there are 2 buildings. They do try to come closer but:
• The gravitational attraction is too small hence ensuing acceleration is too small. The displacement caused by this small acceleration is too small to perceive.
• They are fixed to ground by foundation hence can't move.
• Even if we consider objects that are not fixed to ground, the friction between the objects and ground is high, sufficient to withstand gravitational attraction.

And in an atom two electrons of same or different orbital repel each atom why don’t they go away
Answer
Positive nuclei attract both of them.
