Unsure about answer

A proton (m = 1.67 x 10^-27 kg) is suspended at rest in a uniform electric field E. Take into account gravity at the Earth's surface, and determine E.

I did this problem already but I'm not sure if it's correct...
I used the equation: E = F / q = ma/e to get an answer of 1.02 x 10 ^-7

Is this correct?
