Question

what is coulomb law ---??​

Answer 1

$\large\underline{\pink{\sf \orange{\bigstar} Concept\: Of \: Coulomb \: Law:-}}$

• ◈ Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.

• >> Formula : F = Kq1q2 / r²

$\large\underline{\blue{\sf \purple{\maltese} Where:-}}$

• ◈ F = electric force

• ◈ k = Coulomb constant

• ◈ q1, q2 = charges

• ◈ r = distance of separation

Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.

Coulomb's law is also relevant to the interactions between atomic nuclei. Two positively charged nuclei will repel each other due to the coulomb force unless they are close enough that the strong nuclear force (which causes the protons to attract instead but only acts at a very short range) wins out.

Coulomb, unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units. ... The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere.

LIMITATIONS OF COULOMB'S LAW:

1)Applicable only in cases when inverse law works.

2)It is Difficult to apply Coulomb's Law,when charges are in arbitrary shape.
