: 8 Cyu Figure 18 2 Shows Three Point Charges Arranged In Three Different Ways The Charges Are Q Q And Q Each Has 1 (40.68 KiB) Viewed 12 times

I got the answer the answer is C>A>B.
A is (1.25)Kqq0/r2
B is zero since each vectors cancel each other(plz correct me ifi am wrong)
But I don't know how to solve C (the answer is(1.4)Kqq0/r2)
Please provide the answer with great details, stuck with thisquestion for a while

8. CYU Figure 18.2 shows three point charges arranged in three different ways. The charges are +q, -q, and -q; each has the same magnitude, with one positive and the other two negative. In each of the arrangements the distance d is the same. Rank the arrangements in descending order (largest first) according to the magnitude of the net electrostatic force that acts on the positive charge. +q d A -9 ∙q d +q B d -9 d 9 +q 90° d C
