### Post-assessment question 34

I got 1.00 x 10^-5 m/s and thought it was reasonable since it is smaller than the speed of light. Could anyone explain why this is wrong?

I believe the answer was 1.00 x 10^5m/s, not the answer you gave. The rest of you answer is correct, in that it is reasonable because the electron is moving slower than the speed of light.

okay thanks! One more thing, if the answer was 10^-5, would it still be reasonable?
