Question

Two isolated metallic solid sphere of radius r and 2r are charged such that both of these have same charge density . The spheres are located far away from each other and are connected by a thin conducting wire. The new charge density on the bigger sphere is

Answer 1

First you have to know the concept to use here....Your answer will come...new charge density on bigger sphere will be 5/6 times of initial density on bigger sphere....

See whenever we touch metallic conductors with the help of wire, always remember that in between both spheres charge distribution will takes place till their potential becomes equal(you should know the formula of finding potential difference ) I am attaching pics...please refer them for clear explanation....For any query feel free to ask.....

If i am wrong...please mention that too.....I m too learning and will keep on learning....
