Electric field strength

What is the electric field strength at a point in space where a proton experiences an acceleration of 1 million "g"?

I'm completely lost on this one I know it's bound to be something simple but I just can't figure out where to start with it, well other than that 1 million "g" should be 9.8x10^6 m/s^2

I'm also not quite sure, but I'm guessing this will have something to do with gravitational fields.

The question seems to infer that the proton is accelerated by the electric field.

Think about the relationship of Force to the electric field strength and as a function of mass and acceleration.

[tex]\vec{F} = m\vec{a} = q\vec{E}[/tex]

okay, so I get...

ma = (1.64x10^-21)/(1.6x10^-19) = 0.01N/C

would that be right?

U missed one order of size:
[tex] |\vec{E}|=\frac{m_{proton}|\vec{a}|}{q_{proton}} [/tex]
[tex] |\vec{E}|=\frac{1.67\cdot 10^{-27}Kg\cdot 9.8\cdot 10^{6} ms^{-2}}{1.6\cdot 10^{-19}C}\sim 0,1N/C [/tex]
