Coulomb's law describes how the charge on and distance between two
particles affect the electric force between them. When both particles have a positive charge the situation will result in two particles being repelled by each other, the correct option is A.
What is Coulomb's law?
Coulomb's law can be expressed as that the electrical force between two charged bodies is directly proportional to the product of the quantity of charge on the bodies and inversely proportional to the square of the separation distance between the two bodies.
The mathematical expression for Coulomb's law is expressed as
F=kQ₁Q₂/r²
F is the electric force
k is the Coulomb constant
Q₁ and Q₂ are the charges
r is the distance of separation between the charges
In accordance with Coulomb's law when both particles have a positive charge the situation will result in two particles being repelled by each other, therefore the correct option is A.
