A charge +Q is placed on a large spherical conducting shell of radius R. Another small conducitng concentric sphere of radiur r carrying charge q is placed inside the shell. Find the potential difference between two points. One lying on the sphere and the other on the shell.

Two uniformly charged concentric spherical shells of radius R and r, are given charges Q_1 and Q_2 respectively. If their potential difference is V, then it will not depends upon:
