Two insulated charged spheres of radii 20 cm and 25 cm respectively and having an equal charge Q are connected by a copper wire. Then they are separated. Which of the following is correct?
Text Solution
Verified by ExpertsThe correct answer is:
C
The potential of the spheres on separation will be same. Also the capacitance is proportional to the radius. So capacitance of sphere having radius 25 cm is more. Since 
, therefore q for 25 cm sphere is more.
