A man stands 6.0 ft tall at sea level on the North Pole as shown in Figure P5.62. (a) What is the difference in the value of g (the gravitational acceleration) between his head and his feet? (b) The man is now put in a space suit and transported to a location one Earth radius away from a black hole of mass equal to 20 times the mass of our Sun. If the man’s feet are pointing in the direction of the black hole, what is the difference in the gravitational acceleration between his head and his feet? Would this difference in acceleration be harmful, just noticeable, or somewhere in between?
