Answer 1

Answer:

The mass of the moon is 18 of the earth but the gravitational pull is 16 earth It is due to the fact that . Where the subcipts M and E are for the moon and the earth respectively.

Answer 2

The mass of the moon is (1/8) of the earth but the gravitational pull is (1/6) of the earth. It is due to the fact that:

A .

moon is the satellite of the earth

B .

the radius of the earth is (8/6) of the moon

C .

the radius of the earth is (8/6) of the moon

D .

the radius of the moon in (6/8) of the earth

gEgM=RE2GMERM2G(ME/8)=8RM2RE2              ....(i)

where the sunscripts M and E are for the moon and the earth respectively.

Given, gEgM=61                             .....(ii)

From (i) and (ii), we get

8RM2RE2=61 or
