Free Response:
An electron is fired at a negatively charged infinite plane with an initial speed of 6.5 × 107 m/s. The plane has a surface charge density of σ = −2.0 µC/m2 .
a) How far does the electron travel before it stops?
b) Which point is at a higher potential, the starting point or the ending point?
c) Do a) and b) for a proton with the same initial speed fired at a positively charged plane with a charge density σ = 2.0 µC/m2 .
