Every object in this universe, whether small or large exerts a force on every other object. What is the name of this force?
Electrostatic force
Gravitational force
Magnetic force
All the above
All objects in the universe exert a gravitational force on all other objects.
The universal law of gravitation states that every object exerts a gravitational force of attraction on every other object. If this is true, why don't we notice such forces? Why don't the two objects in a room move towards each other due to this force?
If the gravitational force is acting on each and every object in this universe then why is the space expanding?
