State columns law define one column​

Answer 1

Answer:

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.

hope this helps

Answer 2

Coulomb's law

Coulomb's law states that the 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.

$\sf F=\frac{q_1q_2}{r^2} \\\\\sf Hence, F \propto q_1q_2 ~and~F \propto \frac{1}{r^2}$

One coulomb

It is the amount of charge transferred in one second by a current of one ampere.

It is equivalent to $6.415\times10^{16}$charges.
