- Homework Statement
- A charge of 2.0 microcoulombs is positioned at (0,0) and a charge of -6.0 microcoulombs is positioned at (3,0). Where must a third charge be placed in order to be in electrostatic equilibrium?
- Relevant Equations
- Electrostatic Force = kq1q2/d^2
I set the electrostatic force exerted by the object at (0,0) and (3,0) equal to each other, dividing out k and q2. I was left with q1/d^2 for both terms and substituted in the given charges for each object. I then replaced d^2 for the object at (0,0) with “x^2” and d^2 for the object at (3,0) with “(3-x)^2”. I got an answer of (1.098, 0) which made sense that it would be somewhere left of 1.50, but was incorrect.
Any helpers in where I went wrong? Thanks.
