Answer 2

Answer:

a Given,

Gravitational force,F= GM m/r² where m and r is variable.

If r increase , keeping F= constant.

F= GM m/(4r) ²

GM m/r²= GM m/16r²

m =16m

b g

1 An acceleration produced on a freely falling body due to the gravitational force of earth is known as acceleration due to gravity.

2 Value of g near earth's surface is 9.8 ms- 2. It may vary from one place to place.

3 Depends upon the distance between the masses

4 SI units is ms ²

G

1 Gravitational constant G is numerically equal to the force of gravitational that exists between two bodies of unit mass kept at a unit distance from each other.

2 Value of G is 6.67 × 10-11 Nm²kg-2 and it is an universal constant.

3 Independent of the distance between the masses

4 SI unit is Nm²kg-2
