Question

x Determine the net force on charge A, located at the origin, due to charges B, C, and D (see figure below 5.34e-3 N y (m) x 6 m 8 m x (m) +3 uC 2 HC Charge A (qA +3 x 10 C) is located at the origin of a coordinate system. Charge B (ge -A x 10 C) is fixed at x 3 m; charge c (gc 2 x 10 6 C) is fixed at x 6 m; and charge D (gD +6 x 10 6 c) is fixed at x 8 m. We can use Coulomb's law to calculate the magnitude and directinn nf the net tarce on A due to the other charges. The unit vectors trom B to A, Cto Ar and D to A all point in the x direction eBook

Explanation / Answer

Net Force acting on charge A due to charges B,C and D is

FA=FB+FC+FD=KQA[|QB|/rB+|QC|/rC-|QD|/rD]

FA=(9*109)(3*10-6)[(4/3)+(2/6)-(6/8)]*10-6

FA=0.02475 N

In unit vector notation

FA=(0.02475 N)x^
