There are two identical, positively charged conducting spheres fixed in space. The spheres are 42.0 cm apart (center to center) and repel each other with an electrostatic force of ?1=0.0630 N. A thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed, the spheres still repel, but with a force of ?2=0.100 N . The Coulomb force constant is ?=1/(4??0)=8.99×109 N⋅m2/C2 . Using this information, find the initial charge on each sphere, ?1 and ?2, if ?1 is initially less than ?2.
