Homework Help: Physics

Posted by Alaine' on Saturday, May 5, 2012 at 9:59am.

A -10 mC charge experiences a force of 75 N directed south. What is the electric field magnitude and direction at the location of the charge?

If this charge is removed and not replaced, what is the electric field magnitude and direction at the location it used to occupy?

I know for the first question it's 7500 north but I don't understand the second portion. How do you calculate the magnitude and direction if the charge is removed?
