How does the electric force between two charged particles change if one
particle's charge is reduced by a factor of 3?

^ Similar/same question as yours!

The pressure between two costs is proportional to the product of the charges.

If solely one of the expenses is decreased by way of a element of 3, then the pressure is decreased with the aid of a thing of 3.

If each prices are reduced by a thing of 3, then the pressure is reduced via a issue of 9.

a, c, d, e are all applying about success strategies.
