Three point objects with net charge of Q1 = +78 µC, Q2 = +47 µC, and Q3 = -80 µC, respectively, are placed along a straight line. The object in the center, (with a charge of Q2), is 0.35 m from each of the others with Q1 to its left and Q3 to its right. Calculate the net force on each charge due to the other two. (State both magnitude and direction.)
