If the mass of a body is M on the surface of the Earth, the mass of the same body on the surface of the Moon is
6 M
zero
M
Variation of acceleration due to gravity (g) with distance x from the centre of the Earth is best represented by (R → Radius of the Earth)
D.
The value of g is maximum at the surface of the Earth and g = 0 at centre of the Earth. If one goes away from the Earth surface, again the value of g decreases. Thus, graph (d) is the correct variation of g.
The value of acceleration due to gravity at a depth of 1600 km is equal to
4.9 ms-2
9.8 ms-2
7.35 ms-2
19.6 ms-2
