Question

a bottle and a glass are kept 30 cm apart on a table as show
(a)Draw the direction of gravitational force that the bottle exerts on glass
(b)Explain why they do not move towards each other although they attract each other with a gravitational force ​

Answer 1

Answer:

You know why they say gravitational force is the weakest of the four fundamental forces?

Because it is. By a laaaarge margin.

Gravity is super, super weak. The only reason it works in the scale of planets is because they are indeed planets, with huge masses to produce a lot of force.

Proof? Magnets. A single little magnet can beat the gravitational force of the whole planet. Place a little piece of metal on the ground, use a little magnet and bam! Gravity loses.

But really, on our local, human everyday life scale, the gravitational force of random objects is completely negligible. And definitely way weaker than the friction of the resting surface.
