A set of charges are arranged in the following way: a 10.0 nC (nanocoulomb) positively charged particle sits at the origin of a coordinate system. A second positively charged particle of 5.00 nC lies along the (positive) x-axis a distance of 0.250 m from the origin. A third and negatively charged particle of -2.50 nC lies a distance of 0.150 m from the origin on the negative y-axis.
A. Sketch a diagram of this charge configuration
B. Calculate the electric field the second and third charges create at the origin.
C. Find the magnitude and direction of the force on the particle at the origin.
