Question

The electrostatic force is the attractive or repulsive force between two electrically charged objects
Like charges repel each other while unlike charges attract each other.
Objects or things fall towards the earth because it pulls them. This force is called the force of gravity, or just
gravity
Gravity is not a property of the earth alone.
In fact, every object in the universe, whether small or large, exerts a force on every other object.
This force is known as the gravitational force.
F: CONCEPT OF PRESSURE
The perpendicular force acting on a unit area of a surface is called pressure.
P = FIA
SI unit of Pressure is Pascal (Pa).
