The figure shows four electrical charges located at the corners of a rectangle. like charges, you will recall, repel each other while opposite charges attract. charge b exerts a repulsive force (directly away from b) on charge a of 3.0 n. charge c exerts an attractive force (directly toward c) on charge a of 6.0 n. finally, charge d exerts an attractive force of 2.0 n on charge a.
assuming that forces are vectors, what is the magnitude of the net force f exerted on charge a?
