[SOLVED] Conservation of Energy
A proton (charge e, mass = 1.67 * 10^-27 kg) accelerates from rest by crossing a potential difference V = 3.00 V
a.) Find the velocity v_0 it acquires?
(Suppose this proton, having initial velocity v_0 from part (a), moves from very away directly towards a stationary heavy ion which is singly charged, i.e. having the same charge as the proton, +e.)
b.) Find the distance r_min between the proton and the ion at the moment of closest approach?
c.) Find velocity v of a proton when it is at a distance r = 2r_min from the ion
a = (q/m)E
V = kQ/r
V = E*d (parallel plate)
I am literally stuck for part a into determining what it could be, it seems something is missing in the problem.
Please help.
Thanks!
