A proton is traveling horizontally to the right at 4.10×10^6 m/s.
Part A: Discover (a) the magnitude and (b) direction of the weakest electric field that can bring the proton uniformly to rest over a distance of 3.10 cm.
Part B: counter clockwise from the left direction
Part C: How much time does it take the proton to stop after entering the field?
Part D: What minimum field ((a) magnitude and (b) direction) would be required to stop an electron under the conditions of part (a)?
