2. Two point charges q1 = +2 C and q2 = -3 C are fixed in place along the x-axis, as shown. 91 = +2 C 92 = -3 C X = 0 X = a You have in your hand another point charge q, and you want to place it somewhere on the x-axis. But you want to place it at a point where it will stay. That is, you want to place it at a point where it will feel no force due to the fixed charges qi and q2. (Hint: Think about what the force looks like very close to each charge and what it looks like very far away from both charges.)
