Question

derive an expression for acceleration due to gravity of the surface of earth in terms of massand radius of earth​

Answer 1

Answer:

answer is

Explanation:

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.

Answer 2

Answer:

Explanation:

Mass of the earth = 6.0 x 1024 kg; mean radius of the earth = 6.4 x 106 m; G =6.67 x 10-11 N m2 kg-2. Acceleration due to gravity at the surface of the earth = 9.8 m/s2. When a body is thrown a body in the upward direction, the kinetic energy of the body converts into potential energy.
