Questions
A metallic sphere of radius R is charged to a potential V. If is brought in contact with an uncharged metallic sphere of radius R/2 and then separated. Then potential of the smaller sphere will be
detailed solution
Correct option is A
Initial charge on the larger sphere Q=4π∈oR. V∴potential of the smaller sphere V'=QC1+C2=4π∈oRV4π∈oR+4π∈oR/2⇒V'=2V/3.Talk to our academic expert!
