Two insulated charged conducting spheres of radii \[20\,cm\] and \[15\,cm\]respectively and having an equal charge of \[10\,C\] are connected by a copper wire and then they are separated. Then [MP PET 1997]

• A.                    Both the spheres will have the same charge of \[10\,C\]
• B.                    Surface charge density on the \[20\,cm\] sphere will be greater than that on the \[15\,cm\] sphere
• C.                    Surface charge density on the \[15\,cm\] sphere will be greater than that on the \[20\,cm\] sphere
• D.                    Surface charge density on the two spheres will be equal
