surface. If the objects are kept at the same separation
on the moon's surface, the force of gravitation
between them will be .......
3. If the distance between two objects is doubled, the
force of gravitational attraction between them
becomes ...... of its initial value.
4. The force of gravitation between two spherical
bodies is Gm, m2/r2, where r is the separation
between their ...
5. If the earth shrinks, thus decreasing its radius, the
value of g at its surface will .......
6. The unit of weight is ...... .​

Answer 1

Answer:

If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

Answer 2

Answer:

1) gravitational force.

2)
