Q: A Point charge q is located at a distance ‘r’ from the center ’o’ of an uncharged conducting spherical shell of inner radius R1 and outer radius R2 respectively.(r<R1). Assume potential to be zero at infinity.
a) The potential at point ‘O’ is b)Electric potential of the conductor is c) Electric potential at a point outside the shell at a distance r0 from center of shell
