[SOLVED] speed of two protons (I think an easy question)

Homework Statement



If you release two protons from rest 1.500nm apart, calculate the top speed, relative to you, that either proton will achieve.

Homework Equations



F=ma

ke^2/r=mv^2 where k=9.0e9 Nm^2/C^2 and e is the charge

The Attempt at a Solution



mass proton = 1.67e-27
charge proton = 1.60e-19

So just plug in and solve for v=

v= [(9e9)((1.6e-19)^2/(1.5e-19))/1.67e-27]^1/2

v=9.59e3 m/s

I just wanted to make sure the process I used for this problem was correct...

Thanks!

Looks good.

Just one typo ( r = 1.5e-19 ? ), but you did use the right number in the calculation.
