[SOLVED] speed of two protons (I think an easy question) 1. The problem statement, all variables and given/known data If you release two protons from rest 1.500nm apart, calculate the top speed, relative to you, that either proton will achieve. 2. Relevant equations F=ma ke^2/r=mv^2 where k=9.0e9 Nm^2/C^2 and e is the charge 3. 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!
