(8%) Problem 5: Consider the arrangement of three point charges in a right triangle shown in the figure, which have charges q1 = 8.5 UC, q2 = -51 uC, and q3 = 25 JC. The distance between q1 and + 93 92 is 36 cm and the distance between 92 and 93 is 76 cm. Randomized Variables 91 = 8.5 JC b 92 = -51 JC 93 = 25 JC a = 36 cm b = 76 cm + a 92 Otheexpertta.com A 50% Part (a) How much potential energy, in joules, is stored in this configuration of charges?
