Two insulated charged conducting spheres of radii 
and 
respectively and having an equal charge of 
are connected by a copper wire and then they are separated. Then
A
Both the spheres will have the same charge of 
B
Surface charge density on the 
sphere will be greater than that on the 
sphere
sphere will be greater than that on the sphere
C
Surface charge density on the 
sphere will be greater than that on the 
sphere
sphere will be greater than that on the sphere
D
Surface charge density on the two spheres will be equal
Text Solution
Verified by ExpertsThe correct answer is:
C
After redistribution, charges on them will be different, but they will acquire common potential
i.e. 
⇒ ⇒ 
As 
⇒ ⇒ 
⇒ ⇒ 
⇒ ⇒ 
i.e. surface charge density on smaller sphere will be more.
