Thank you!

So it would be like this? Q2 going to Q both components would be positive Q1 going to Q the X component would be positive (cosine is positive in the 4th quadrant) and Y component would be negative( sine is negative in the 4th quadrant)

this is what i drew

I did but according to my sketch all four would be positive. I'm doing something wrong I'm not sure what it is because one of them is supposed to be negative, one of the y components

Homework Statement Two equal positive charges, both q = 2.0 × 10−6 C, interact with a third charge, Q = 4.0 × 10−6 C, as shown in the figure above. What is the magnitude of the electric force on Q? (kC = 8.99 × 109 N•m2/C2) Homework Equations I'm confused about assigning signs when I get to...

Thank you! This helped so much

When I'm solving a superposition principle problem i get stuck and so confused with the signs. For example this problem Consider three point charges at the corners of a triangle, as shown at right, where q1 = 6.00 × 10−9 C, q2 = −2.00 × 10−9 C, and q3 = 5.00 × 10−9 C. Find the magnitude and...
