A positive charge of 9 µC exerts and attractive force of 1 N on an unknown charge 0.8 m away. The unknown charge in µC:

Could I get help seeing how to solve this problem?

What is Fx on the charge at x = 16.00 cm if q = 2.650 C? Other charges are at 6000 cm and 2200 cm. Positive is correct. 8.988 109 Nm2/C2 is Coulomb constant. Fx || +0 3.506 Wrong +q 10.00-29 20.00+qx (cm)
