An electron is relased into a uniform electric field of magnitude 8.35 N/C. How many times larger is this electrons acceleration than the acceleration due to gravity on the surface of Earth?

Question

Is it just F= qE = ma (for the electron, and using E for electric field), and then take the a as a ratio of g? It seemed too simple, I'm afraid I'm missing a variable.

Answer 1

set qE=mg*k
solve for k

Answer 2

Hi, I tried this question...should we use g as -9.8m/s^2?
