Charged Particles A & B

1. The problem statement, all variables and given/known data
-A charged particle A exerts a force of 2.62 micro coulombs to the right on charged particle B when the particles are 13.7 mm apart. Particle B moves straight away from A to make the distance between them 17.7 mm. What vector force does it then exert on A?


2. Relevant equations
This is what I am trying to figure out. I'm sort of new to this whole electromagnetism thing.


3. The attempt at a solution

"A charged particle A exerts a force of 2.62 micro coulombs..."

The units of force are newtons (typo)?; coulombs are units of charge.

To work thos probelm, use the equation that relates the electric force to charge and charge separation.

yeah that was a typo thanks
