A thin spherical indulating shell of radius R caries a uniformly distributed charge such that the potential act its surface is `V_(0)`. A hole with small area `alpha4piR^(2)(alpha lt lt 1)` is made in the shell without effecting the rest of the shell. Which one of the following is correct.

A thin conducting spherical shell of radius R has a charge Q which is uniformly distributed on its surface . The correct plot for electroistatic potential due to this spherical shell is ………… .

There is a ball of radius r having uniformly distributed volume charge Q on it and there is a spherical shell of radius r having uniformly distributed surface charge Q on it. The two spheres are far apart. (a) A point charge q is moved slowly from the centre of the shell (through a small hole in it.) to the centre of the ball. Find work done by the external agent in the process. (b) The two spheres are brought closer so that their centers are separated by 4r. Now calculate the amount of work needed in slowly moving a point charge q from the centre of the shell to the centre of the ball. Assume that charge on one ball does not alter the charge distribution of the other. Does your answers in (a) and (b) differ? Why?
