Two identical conduction spheres, one having an initial charge +Q and the other initially uncharged, are brought into contact.  (a) What is the new charge on each sphere?  (b) While the spheres are in contact, a positively chaged rod is moved close to one sphere, causing a redistribution of hte charges on the two spheres so the charge on hte sphere closest to the rod has a charge-Q. What is the charge to the other sphere?
