A charge of - 0.580uC exerts an upward force of magnitude 0.170N on an unknown charge which is a distance of 0.300m directly below it.
A) What is the unknown charge (magnitude and sign)? Use 8.85×10?12C^2/(Nm^2) for the permittivity of free space.
B) What is the magnitude of the force that the unknown charge exerts on the charge of magnitude 0.580uC?
C) What is the direction of the force that the unknown charge exerts on the charge of magnitude 0.580uC?
