Question

obtain an expression to find valve of g.

​

Answer 1

Answer:

Its value near the surface of the earth is 9.8 ms-2. Therefore, the acceleration due to gravity (g) is given by = GM/r2.

...

Under the gravitational influence on two bodies, the mass in terms of mass is given by,

1. FA = GMmA/r2,
2. FB = GMmB/r2,
3. mB = [FB/FA] × m. A

Answer 2

Answer:

Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
