QUESTION:
In Fig. 21-23, three charged particles lie on an x axis. Particles 1 and 2 are fixed in place. Particle 3 is free to move, but the net electrostatic force on it from particles 1 and 2 happens to be zero. If L23 # L12, what is the ratio q1/q2? L12 L23 1 2 3 x Figure 21-23 7 and 40.
ANSWER:Step 1 of 4
Let . The sum of the forces on particle 3 is zero, so the electrostatic force of particle 1 on particle 3 is the negative of the electrostatic force of particle 2 on particle 3.
Our task is to determine the ratio of .
