Now, you need an equation that relates electric field, E, charge, q, and distance from the charge, r. There's one that does it. (Oh, it will have a proportionality constant, too.)

You'll need to figure out the distance you want to use and plug in numbers.

There are two charges, +Q and -Q, that form an electric dipole. Use the principle of superposition. Calculate the E field created by +Q at r = 0.03 m, keeping in mind the direction of the field, and likewise with -Q. Add these two vector values and this will give you the desired result.
