To calculate the magnitude and direction of the electric force on each of the three point charges, we can use Coulomb's law, which states that the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.The formula for Coulomb's law is:
where:- F is the electric force between the charges- k is the Coulomb constant, which is approximately
-
and
are the charges- r is the distance between the chargesLet's calculate the electric force on each charge:1. Electric force on
