Physics 2 Charges what is the magnitude at point P
posted by Mike .
Two charges, Q1= 3.20 microCoulombs, and Q2=5.90 microCoulombs, are located at points (0,2.00cm) and (0,+2.00cm.
What is the magnitude of the electric field at point P, located at (5.00cm,0), due to Q1 alone?

what is the distance from 0..02 to .05,0?
distance= sqrt((.05^2)+(.02)^2) check that.
then E=kq/distance^2
