question

Two equal conducting spheres of negligible size are charged with 16.0 × 10^\rule{1em}{1pt}14C and \rule{1em}{1pt}6.4 × 10^\rule{1em}{1pt}14 C, re-spectively, and are placed 20 cm apart. They are then moved to a distance of 50 cm apart. Compare the forces between them in the two positions. The spheres are connected by a thin wire. What force does each now exert on the other?
