You are given a uniformly charged spherical shell that has a radius 'R' and carries a positive charge 'q'. In order to measure the electric field magnitude inside you drill a small hole that removes 0.01% of the shell's material and insert a probe into the shell. What is the approximate magnitude at the shell centre?
Express your answer in terms of the Coulomb's law constant 'k' and some or all of the other variables q, R.

E=?
