We know, for determining the electric field at r>R for a conducting sphere, the sphere can be considered as a point charge located at its centre.
Also, electric field intensity at a point P, located at a distance r, due to net charge q is given by,
Given, r = 20 cm = 0.2 m (From the centre, not from the surface!)
Therefore, Charge on the conducting sphere is
(Since flux is inwards)
