Solution Summary

This solution involves finding the location where the total electric force on a given positive charge is zero in a region of two negative charges.The solution to this question includes a complete and clear step-by-step answer, along with a diagram.

Solution Preview

Any positive charge placed to the left of -3.50 nC charge or to the right of the -6.30 nC charge would not experience a net zero electric force. However, placing a positive charge in the region between the two charges could produce a net zero electric force.
