There are two charges q1 and q2. They are horizontally 13 cmawayfrom each other. There is a point P above them both. The pointP is5 cm away from q1 and 12 cm away from q2. The point P, q1 andq2make right triangle (the 90 degree angle is where point P isat).The magnitude of q1 is 3 micro coulombs but the sign of it isnotknown. Both the magnitude and sign of q2 are not known. Thenetelectric field is said to be entirely in the negative ydirection.What is the net electric field?
I have tried this question many times and can not get therightanswer. I know that both the charges are negative. I havefound allthe angles. I do not know what I am doing wrong. Pleasehelpme.
