Marlon Conway · Answer 1

The force of attraction between two charged particles is given by the Coulomb's law which may be written as,

F = k (Q1) (Q2) / (d^2)

If the charges in both are doubled, the expression would be,

F = k (2) (Q1) (2) (Q2) / (d^2)

We can conclude that by doing so, the force of attraction is multiplied by 4.
