A small object of mass 3.80 g and charge -18uC (-18 x 10^-6 or microcoulombs) "floats" in a uniform electric field. What is the magnitude and direction of the electric field?
F = ma
F = Eq
The Attempt at a Solution
I already have the magnitude down. It's 2070 N/C
Why does the electric field point down though? I don't fully understand the direction of electric fields with positive or negative charges in them. can someone explain this to me?
