I need solve this assignment

[10 Points] Two charges q] and q; are placed to either end of the hypotenuse of a right triangle, with a = 3 [cm], b = 7 [cm] and c = 7. 62 [cm], as shown in the gure. The magnitude of q] is 2 Inc] but its sign is unknown. At point P, the direction of the net electric eld E. created by the two charges, is entirely in the negative y- direction. C a.
