Question Details:

Two point charges are placed on the x axis.

The first charge, q_1

= 8.00

, is placed a distance 16.0

from the origin along the positive x axis; the second charge, q_2

= 6.00

, is placed a distance 9.00

from the origin along the negative x axis.

Part A

part B

Part A

Find the electric field at the origin, point O.

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.

$E_{{\rm O}x}, E_{{\rm O}y}$ =

$\rm{N/C}$

Part B

Now, assume that charge q_2

is negative; $q_2 = -6 \; \rm {nC}$ .

What is the net electric field at the origin, point O?

$E_{{\rm O}x}, E_{{\rm O}y}$ =

$\rm{N/C}$
