Sign and repulsive if the charges are of the same sign. Now add a fourth charged particle, particle 3, with positive charge q3, fixed in the yz-plane at (0, d2, d2).
What is the net force F→ on particle 0 due solely to this charge? Express your answer (a vector) using k, q0, q3, d2, i^, j^, and k^. Include only the force caused by particle 3.
