The point charge at the bottom of the figure is Q = + `Q` nC, and the curve is a circular arc. What is the magnitude of the force on the charge Q due to the other point charges shown? (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2 and 1 nC = 1 × 10-9 C) Hint: First draw the force vectors on Q due to the 3 charges (opposites attract, like repel). Then calculate the magnitude of the force between Q and each of the three charges. Then break them into x- and y- components and make sure you have the correct sign for each component (positive for components pointing to the right or up, and negative for components pointing to the left or down). For example F12x = |F12|cos(angle) and choose the correct sign for that component. Finally, add all the x’s together and all the y’s together. Those are the components of the total force on Q. Then find the magnitude of that vector. Give your answer in units of N (1 N = 10-6 N) and round to the nearest whole number.
