Five charges are placed in a closed box. Each charge (except the first) has a magnitude which is twice that of the previous one placed in the box. All charges have the same sign and (after all the charges have been placed in the box) the net electric flux through the box is 4.6 × 107 N · m2 /C. What is the magnitude of the smallest charge in the box?
