Answer:
The question is incomplete as some details are missing, here is the details ;
In this final state
a) spheres #1 and #2 both carry negative charge.
b) sphere #1 carries negative charge and #2 carries positive charge.
c) spheres #1 and #2 are still uncharged.
d) sphere #1 carries positive charge and #2 carries negative charge.
e) spheres #1 and #2 both carry positive charge.
Explanation:
From the concept of electrostatics, if a positively charged sphere is brought close to #2, there will be attraction of the opposite charges(-ve) towards it.
Now connecting a copper wire between #1 and #2, opposite charges will flow from #1 towards #2. disconnecting the copper wire makes #1 to be positively charged and #2 to be negatively charge and from the laws of attraction ; Like charges repel and unlike charges attract. the correct option is d.
