Physics

There are two identical, positively charged conducting spheresfixed in space. The spheres are 38.2 cm38.2 cm apart (center tocenter) and repel each other with an electrostatic force of?1=0.0705 NF1=0.0705 N . A thin conducting wire connects thespheres, redistributing the charge on each sphere. When the wire isremoved, the spheres still repel, but with a force of ?2=0.100NF2=0.100 N . The Coulomb force constant is ?=1/(4??0)=8.99×109N⋅m2/C2k=1/(4πϵ0)=8.99×109 N⋅m2/C2 .
