3) What voltage is required to accelerate protons to a speed of 10^4 m/s ?
(e =1.6E-19C, proton's mass =1.67E-27kg)
(k=9E9 Nm/C^2)
This Q. is from Kaplan's MCAT physics review notes (p.419)
It's in the High-yield problems category under "similar questions," so it did not offer an answer. I worked out an answer but could not find a way to confirm it. (I did it by using conservation of energy.) I want to see if anyone else could work the problem and can arrive an answer that matches mine, so I can finally get it off of my head .
