Homework Equations



No equations are given. Assumed use of standard equations for electric field and force involving electric field.

The Attempt at a Solution


I tried using a few equations (E = F/q0), (F = mv^2), (E=(1/(4piEp0))(q/r^2)), and solving, but no luck. Could someone please give me guidance?

If you can determine the force F acting on the charge, and this force acts on the proton over a distance of 7 cm, how much work is done?
 
Alright so I just remembered the simple equation F = qE so now I'm going to attempt what you said. Physics is not my strength however, so I will probably be back.

No worries, we'll be here!
 
Thank you for your tip. I was able to solve it!
 
Excellent.
