Charge inside and outside conducting shell

[Utsavdutta98]

A thin metallic spherical shell contains a charge Q over it. point charge +q is placed in side the shell at point T separated from the centre by a distance a. Another point charge q1 is placed outside the shell at a distance b from the centre find the electric field at the centre due to the charge over outer surface of the shell and the net field at the centre.
