Two charges, Q1= 3.20 microCoulombs, and Q2=5.90 microCoulombs, are located at points (0,-2.00cm) and (0,+2.00cm.

Question

What is the magnitude of the electric field at point P, located at (5.00cm,0), due to Q1 alone?

Answer 1

what is the distance from 0.-.02 to .05,0?

distance= sqrt((.05^2)+(.02)^2) check that.

then E=kq/distance^2
