SUMMARY
The net force on the -1nC charge in the given Coulomb's Law problem is calculated using Coulomb's Law and trigonometric equations. The force between the two known charges is determined to be 1.44x10^-4 N, with a downward component calculated as 1.25x10^-4 N. The error in the initial calculation arises from misunderstanding that the net force must account for the contributions from both known charges acting on the -1nC charge. The correct approach involves summing the forces from both charges to find the total net force.
