State and explain coulombs law of electrostatics?

Answer 1

According to conservation of electric charge ,the total charge on an isolated system remains constant.

( By isolated system we mean the system in which there is no external disturbance i.e.,there is no charged or uncharged conductor in the neighbourhood and hence no leakage of charge).

Here is the example of conservation of electric charge in radioactive decay.

92U238 (Parent atom) ------->(decays) 90U234(daughter atom) + 2He4(alpha particle)

The amount of charge present before decay is 92e and this is equal to the amount of charge after the decay ( 90e + 2e = 92e).Hence electric charge is conserved.

Answer 2

Electrostatics is concerned with the interaction of stationary electric charges and there is more than one law associated with this field of study. Perhaps the most fundamental of these laws is Coulomb's Law, which gives the electric force, F, between two stationary point charges, of charge q1 and q2which are a distance r apart;

Where ?0 is the permittivity of free space.

Answer 3

it states that any two charges separated by a distance experiences one of attraction and repulsionwhose magnitude is directly proportional to the product of the charges and is inversely proportional to the square of the distance between them .

let q1 and q2 be the charges seperated by a distance .r square

Answer 4

You might be referring to the law of conservation of charge. That means that in a closed system, the total charge cannot change.

Answer 5

The total mass of the reactants equals to the total mass of the product.

Answer 6

According to the law of conservation of charge ,the total charge on an isolated system remains constant.

Answer 7

Just like other conservation laws, it means that there is something - in this case, the amount of electrical charge - that won't change over time.

Answer 8

That means that the total charge, in a total system, remains constant - it doesn't get more positive, or more negative.
