80. A small body of superdense material, whose mass is twice the mass of the earth but whose size is very small compared to the size of the earth, starts from rest at a height H<<< R above the earths surface, and reaches the earths surface in time 1. Then t is equal to : 2H H (a) (b) 8 DO 8 2H (c) (d) 3g 81. In the above question if the mass of the body is half the mass of the earth, and all other data remain the same, then t is equal to : 4H 3g (a) (c) 2H 8 DO 2H 3g (b) (d) H DO 4H 3g 80.
