A charge of -3.50 nC n C is placed at the origin of an xy x y -coordinate system, and a charge of 2.30 nC n C is placed on the y y axis at y y = 4.20 cm c m .
A) If a third charge, of 5.00 nCnC , is now placed at the point xx = 3.45 cmcm , yy = 4.20 cmcm find the xx and yy components of the total force exerted on this charge by the other two charges.
B) Find the magnitude of this force.
C) Find the direction of this force.
