Two point charges are placed on the x axis. The first charge, q1 = 8.00 nC, is placed a distance 16.0 m from the origin along the positive x axis; the second charge, q2 = 6.00 nC, is placed a distance -9.00 m from the origin along the negative x axis.
Calculate the electric field at point A, located at coordinates (0m, 12.0m). Give the x and y components of the electric field as an ordered pair
Bold indicates vectors
CA = OA - OC = 12j - 16i
|CA| = 20 m
Unit vector along CA = CA/|CA| = (12j - 16i)/(20) = 0.6j - 0.8 i
|Eca| = kq1/CA2 = 9*109*8*10-9/(400) = 0.18 N/C
Eca = 0.18*( 0.6j - 0.8 i) = - 0.144i + .108j N/C
DA = OA - OD = 9i + 12 j
|DA| = 15 m
Unit vector along DA = DA/|DA| = 0.6i +0.8j
|Eda| = kq2/DA2 = 9*109*6*10-9/225 = 0.24 N/C
Eda = 0.24*( 0.6i +0.8j) = 0.144 i + 0.192 j N/C
E = Eca + Eda = 0.3 j N/C
As orderd pair E = (0 , 0.3 N/C)
