Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 3) 10.0 points Two point charges lie on the y axis. A third charge q is placed somewhere in space such that the resultant force on it is zero. x y 3 μ C 2 m q, | q | = 9 μ C . 26 μ C- 1 . 1 m Where must the third charge lie? 1. The third charge must lie on the z axis (perpendicular to the xy plane). 2. The third charge must lie on the x axis. 3. The two given charges must have opposite signs for the force on the third charge to be zero. 4. The third charge must be equi-distant from the two given charges. 5. The third “charge” must be zero; q = 0. 6. There must be an additional charge (fourth charge) to balance the unresolved force on the third charge. 7. The two given charges must have the same sign for the force on the third charge to be zero....
