State whether the following statement is true or false :
The value of G on the moon is about one-sixth `(1/6)`of the value of G on the earth.
Write scientific reasons.
The value of g at the centre of the earth is zero.
The mass of the moon is `1/81` of the mass of the earth. Its diameter is `1/3.7` of that of the earth. If acceleration due to gravity on the surface of the earth is 9.8 m/s2, then the acceleration due to gravity on the surface of the moon.

The value of gravitational acceleration g at a height h above the earth's surface is `"g"/4`, then ______. (R = radius of earth)
If the surface is smooth, the acceleration of the block m2 will be ______.
If the change in the value of g at the height h above the surface of the earth is the same as at a depth x below it, then ______.
(both x and h being much smaller than the radius of the earth)
If the Moon's mass is 1/80 of Earth's mass and its radius is 1/4 of Earth's radius, what is the ratio of g on the Moon to g on Earth?
A monkey of mass 50 kg climbs on a rope which can withstand the tension (T) of 350 N. If monkey initially climbs down with an acceleration of 4 m/s2 and then climbs up with an acceleration of 5m/s2. Choose the correct option (g = 10 m/s2).
The value of acceleration due to gravity at Earth’s surface is 9.8 ms−2. The altitude above its surface at which the acceleration due to gravity decreases to 4.9 ms−2, is close to ______.
