Question
the force between two charges is 20.0 N. if one charge is doubled, the other is tripled, and the distance between them is halved, calculate the resultant force between them.

Force = Q1*Q2/(4πεr²)
So if
20 N = k*Q1*Q2/r²
What is
F=k*(2Q1)(3Q1)/(r/2)² ?
So if
20 N = k*Q1*Q2/r²
What is
F=k*(2Q1)(3Q1)/(r/2)² ?
