Dear shefali


we know potential outside the sphere is V1 = kQ/x     where x is the distance from the center x>r


 and potential inside the sphere V1 = kQ/2r [3-x2/r2]


 for center put x=0  Vo = 3kQ/2r


condition given is V1 = Vo/2


                      kQ/x  = (3kQ/2r)/2


                         x=4r/3


 distance from the surface is  =x-r


                                         = 4r/3 -r =r/3
