Be sure to review Examples 21.3 and 21.4 (Section 21.3) before attempting these problems. Charge q = +3.60 nC is on the z-axis at x = 0 and charge q = -3.00 nC is on the z-axis at x = 6.00 cm. Find the z-component of total electric force exerted by q and q on a third charge q3 = -3.00 nC on the x-axis at 4.00 cm. Express your answer in newtons. F-2.63x104 N Submit Previous Answers Correct VP 21.4.2 Part B Charge q = +3.60 nC is on the z-axis at x = 0 and an unknown charge q2 is on the x-axis at x = -4.00 cm. The total electric force that q and q exert on a third charge qs = +2.00 nC on the x-axis at z = 4.00 cm is in the +x-direction and has magnitude 25.0 N. Find the z-component of the force that q exerts on qs Express your answer in micronewtons.
