Question

Derive an expression for the acceleration due to gravity of the earth. Take mass of the
earth as equal to M and radius of the earth is equal to R.

Answer 1

Answer:

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.
