59. (a) Charge Q 1 = +80 × 10 –9 C is on the y axis at y = 0.003 m, and charge 9 2 80 10 C Q =+ × is on the y axis at y = –0.003 m. The force on particle 3 (which has a charge of q = +18 × 10 –9 C) is due to the vector sum of the repulsive forces from Q 1 and Q 2 . In symbols, 31 32 3 , FF F += GG G where 3 2 22 || , . qq q q Fk rr == Using the Pythagorean theorem, we have r 31 = r 32 = 0.005 m. In magnitude-angle notation (particularly convenient if one uses a vector-capable calculator in polar mode), the indicated vector addition becomes
