Three point charges are arranged on a line. charge q3=+5.00x10^-9c and is at the origin. charge q2=-3.00x10^-9c and is at x=+4.00cm. charge q1 is at x=+2.00cm. what is the magnitude and sign (+ or -) for q1 if the net force on q3 is zero?
a. 0.750 nc
b. 0.520 nc
c. 0.975 nc
d. 0.000 nc

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
