Question

Explain coulomb's law​

Answer 1

Explanation:

✔️ COULOMB'S LAW✔️

➡️ THIS IS QUANTITATIVE STATEMENT ABOUT FORCE BETWEEN CHARGES.

FORCE BETWEEN TWO POINT CHARGE IS

1) DIRECTLY PROPORTIONAL TO THE PRODUCT OF MAGNITUDE OF CHARGES.

2) INVERSELY PROPORTIONAL TO THE SQUARE OF THE DISTANCE BETWEEN POINT CHARGES.

★ The Value of K depends on the nature of the medium between the two charges and the system of units chosen.

★ Forces between point charges acts along line joining them.

★ For point charge :– size << seperation.

Answer 2

Explanation:

electromagnetism and electronics, electromotive force, is the electrical action produced by a non-electrical source. Devices provide an emf by converting other forms of energy into electrical energy, such as batteries or generators. Sometimes an analogy to water pressure is used to describe electromotive force.
