I’m given a diagram. On the diagram on the left is a positive attraction on the right there is a negative. 2 meters from the positive is a bus, or simplified electric transportation. It is running on a 40 m track. The question is as follows… A simplified electric transportation system is shown at right. The 200 kg, 4.0 mC bus is propelled by electrical forces. The two stationary charges have charge magnitude 10 mC.
How fast is the bus moving when it is 2 meters from the other station?
Thank you.
A quick hyperphysics.info search for electric force gives:

The first link has governing equations, diagrams, descriptions, and even an online calculator!
And there is more than just help with electric forces. You can search for help on any type of physics.
Enjoy!
