Hi. As the electric field inside a conductor is zero. The electrostatic potential is constant inside it. The potential at centre will be the potential of entire conductor. The entire charge of conductor is on surface. Note that despite induced charges, net charge will be zero. Thus the net potential at centre is kQ/r (due to surface charge) + kq/2r (due to the point charge) Q=0Thus potential is kq/2r= 9 Volts

hope it helps
thankyou
