Homework Statement


In an experiment you find that a small styrofoam ball of mass m can be suspended in mid-air by an electric field of magnitude c pointing straight downward, towards the earth.

Its looking for the charge on the styrofoam ball, and I have no equation to help me solve for it.


Homework Equations


Lol that's what I'm lookin for.

What is the equation for the force experienced by a charge q in an electric field E?
 
k(q1)(q2) / l^2?
