# Electrostatics: Coulomb's law, Resultant force

Not what you're looking for?

There are 3 electrostatic charges q1=-1Q, q2=2Q and q3=1Q. These charges are placed as follows: q2 is placed at the origin, q1 is placed at a distance +B from the origin on the positive y axis and charge q3 is placed a distance +B from the origin on the positive x axis.

Find the force (magnitude and direction) on q3 due to q1 and q2. Please give the answer in vector notation (Cartesian coordinates)
