Particles A, B, and C, with charges \(12.0 \mu \mathrm{C}, 8.0 \mu \mathrm{C}\), and \(-6.0 \mu \mathrm{C}\), respectively, are evenly spaced along a line, in that order, with spacing \(2.0 \mathrm{~m}\). What is the magnitude and direction of the electric force exerted

(a) on \(\mathrm{A}\),

(b) on \(\mathrm{B}\), 

(c) on C?
