Acceleration due to gravity  at a depth 'd' from earth surface is :                







    
        

                          gd = g(1-          
                              d         
                            )          
        

        

                              R         
        

    












Acceleration due to gravity  at  height 'h' from earth surface is : 

h is very much smaller than R                              




    
        

                          gh = g(1-          
                              2h         
                            )          
        

        

                              R         
        

    












gh = gd

By solving it , d=2h
