7. The electric field above the surface of the Earth is approximately 150 N/C, pointing downward toward the Earth's surface. Suppose a proton is fired from the surface of the Earth at a speed of v = 6.25 X 10" m/s as shown in the figure. a) What is the maximum height the proton reaches? b) When the proton impacts the ground, how far horizontally is it from where it was fired?
