Homework Statement



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 (0 m, 12.0 m).

Homework Equations



E=kq/r2

Calculate the distance from each charge to point A

Determine the directions of the electric fields


Calculate the components of E


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.

The Attempt at a Solution



I am not sure what to do.. I am getting confused with the components.. Can someone show m how to do this?
