Question

Explain :a. electrostatic force and b. gravitational force.

Answer 1

ELOELECTROSTATIC FORCE- Is a branch of physics that studies electric charges at rest since classical physics it has been known that some material such as Amber attract lightweight particles after rubbing electron was source of word electricity address static phenomena arise from the force that electric charges exert on each other search forces described as Coulomb's law. electrostatically include force seem to be brother with some electrostatic force acts as the one between an electron and a Proton that together make up a hydrogen atom is about 36 record of magnitude stronger than the gravitational force acting between them.


Gravitational force- Newton's law of universal gravitation is used to explain gravitational force this law states that every massive particle in universe attract each other massive particles with a force which is a directly proportional to product of their masses and inversely proportional to the square of distance between them this general physical law was derived from observation made by induction another way more mountain way to state the law is every point mass attract every single other point mass by force pointing along the line intersecting both points. The force is proportional to the product of two masses and inversely proportional to the square of distance between point masses.




I hope it will help you.
if not then I'm really sorry from my heart.

Answer 2

Answer:

It is our common experience that some 'muscular effort or force is required when we lift a bucket of water. A ball pressed by hands produces a change in the shape of the ball. To stop a moving body, some force is required. Thus, force is a push or pull which produces or tends to produce a change

It is our common experience that some 'muscular effort or force is required when we lift a bucket of water. A ball pressed by hands produces a change in the shape of the ball. To stop a moving body, some force is required. Thus, force is a push or pull which produces or tends to produce a changein the state of rest or of uniform motion. Force may produce the following changes:
