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

Is my work correct?
