Question: A proton is traveling horizontally to the right at 5.00×106 m/s .
A-B) Find (a)the magnitude and (b) direction of the weakest electric field that can bring the proton uniformly to rest over a distance of 3.30 cm.
C) How much time does it take the proton to stop after entering the field?
D-E) What minimum field ((a)magnitude and (b)direction) would be needed to stop an electron under the conditions of part (a)?
