Two identical small conducting spheres are separated by 0.60 m. The spheres carry different amounts of charge and each sphere experiences an attractive electric force of 10.8N. The total charge on the two spheres is -24 C.
 
  The two spheres are now connected by a slender conducting wire, which is then removed. The electric force on each sphere is closest to A) zero.
  B) 3.6 N, attractive.
  C) 5.4 N, attractive.
  D) 3.6 N, repulsive.
  E) 5.4 N, repulsive.
