A proton is traveling horizontally to the right at5.00×106 m/s . | |
Find (a)the magnitude and (b) direction of the weakest electricfield that can bring the proton uniformly to rest over a distanceof 3.40 cm .
a. E =___N/C
b.∘ counterclockwise from the left direction
c. How much time does it take the proton to stop after enteringthe field?
d. What minimum field ((a)magnitude and (b)direction) would beneeded to stop an electron under the conditions of part (a)?
∘ counterclockwise from the left direction
