Consider the figure with a symmetrical arrangement, in which la = 9b 48.55 μC, q. = qa = -8.55 µC, and q is positive. Using the symmetry of the arrangement, determine the direction of the force on charge q. down and right O right down up down and left up and left up and right left Calculate the magnitude of the force F on the charge q given that the square is 11.40 cm on a side and q 2.05 иС. F = N

A test charge of +3 µC is placed halfway between a charge of +6 µC and another of +9 µC separated by 20 cm. (a) What is the magnitude of the force (in N) on the test charge?  N (b) What is the direction of this force (away from or toward the +6 µC charge)? away from the +6 µC chargetoward the +6 µC charge
