Question

Two point charges are placed on the x axis.(Figure 1) The first charge, = 8.00 , is placed a distance 16.0 from the origin along the positive x axis; the second charge, = 6.00 , is placed a distance 9.00 from the origin along the negative x axis.Give the x and y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant figures. Keep in mind that an x component that points to the right is positive and a y component that points upward is positive.Give the x and y components of the electric field as an ordered pair.

Explanation / Answer

Now the first charge produces a field that is to the left at the origin and the second charge produces a field that is to the right at the origin.. So E = -kq1/r1^2 + kq2/r2^2 = 9.0x10^9N-m^2/C^2*(-8.0x10^-6)/(0.16m)^2 + (6.0x10^-6)/(0.090m)^2) = 3.85x10^6N/C to the right... So answer = (3.85x10^6,0) Again you are unclear about part B Now if the charges are both negative then the answer is (-3.85x10^6,0)
