Three charges are arranged in the (x, y) plane as shown. 6nC at 0,0 ; -2nC at -3,2 and -5nC at -5,-2. What is the
magnitude of the resulting force on the 6 nC charge at the origin? The value of the Coulomb constant is 8.98755 × 109 N · C 2 /m2 . Answer in units of N.
What angle does the resultant force on the 6 × 10−9 C charge at the origin make with the positive x axis? Quadrant I lies between 0 ◦ and 90◦ , quadrant II between between 90◦ and 180◦ , etc.
