The speed at which a proton strikes the positive plate (uniform electric field).

[_Chemicals_]

Homework Statement

Here is the problem given. The answer is E.

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!
