Problem 7: (14% of Assignment Value)
Consider the arrangement of three point charges in a right triangle shown in the figure, which have charges
$$q_1 = 6.5 \ \mu C, q_2 = 57 \ \mu C, \text{ and } q_3 = 35 \ \mu C$$. The distance between $$q_1$$ and $$q_2$$ is 36 cm and the distance
between $$q_2$$ and $$q_3$$ is 78 cm.
$$q_3$$
