Uniform Electric Fields

EtherMD

1. The problem statement, all variables and given/known data
A proton (m=1.67x10^-27) is suspended at rest in a uniform electric field E. Take into account gravity and determine E.


2. Relevant equations
F_E=|q|E
F_g=mg


3. The attempt at a solution
F_G = mg
F_G = (1.67x10^-27)(9.8)
F_G = 1.64 x 10^-26

Since the force on the proton due to the E field is equal and opposite, then:
F_E=|q|E
F_E / q= E
(1.64x10^-26) / (1.6x10^-19) = E
1.04x10^-9 = E

Have you handled your exponents correctly?

Probably not, but does the way I reached my answer make sense?

Yes the steps are correct, just a calculation error.
