Homework Statement
An oil drop is charged negatively. How much charge is on the drop if the Electric Field is 6,400 N/C at a distance of 1.2 m?
Homework Equations
E=k q/r^2
I don't know if I should be using that equation for this one.
The Attempt at a Solution
I tried to do E/(k x r^2) = q but that didn't work
I also tried E/r^2= q but that also didn't work
I know the answer has to be 1.3 x 10^3
Thanks in advance for all the help!
