Coloumbs Laws and electric fields

[SS2006]

Determine the acceleration of a proton (q = +e, m = 1.67 E -27)
in an electric field of intensity 500 N/C. How many times is this acceleration greater then that due of gravity

I'm not so understanding on todays lessons
the 2 formulas I can recall are f = q*e
and e = f/q
but i don't see that helping here, can someone help me start off
thanks guys.

HINT: Force = mass x acceleration

 

[SS2006]

yup i knew of that
i got mass, I am looking for acceleration
but what's force
f = q * e right
i got e just don't know what q is (what they mean by q = +e)

Useful little table there of constants, e is the charge of an electron.

oh roger that
thanks
