Question 2 Consider four point charges. Two are positive; two are negative. The charges Q1-7 C, Q2-10.5 C and Q3-7 C are spaced along the x-axis at the points (-L, 0), (0,0), and (L, 0) as shown in the figure, where L = 1.3 meters. The charge, Q4-10.5 C, is located at the position (0,h) where h - 2.6 m. What is y-component of the force on Q4 due to the other three charges? a. Fo4y - Zero = b. Fo4y 0.00674 N FQ4Y = c. Fo4y -0.00429 N d. Fo4y-0.027 N e. FQ4y=-0.187 N Selected Answer: b Correct Answer: d Q1 h Q Qs 8 X L L
