The electric field at P due to point charge -q and induced charge -q is zero- not due to induced charge -q on the cavity surface-If we-xA0-select a gauss-apos-s surface-xA0-up-to-xA0-P- we can see the net charge is zero - so-xA0-what ever electric-xA0-field will be there will be due to induced-xA0-charge on outer-xA0-surface-xA0-q-xA0-

The electric field at P due to point charge +q and induced charge -q is zero, not due to induced charge -q on the cavity surface.If we select a gauss's surface up-to P, we can see the net charge is zero , so what ever electric field will be there will be due to induced charge on outer surface (+q)
