Question

State newton's law of gravitation and calculate value of g

Answer 1

Answer:

Given below

Explanation:

Newton's Law of Gravity says that the force between two masses, and that's the gravitational force, is equal to the gravitational constant G times the mass of the first object times the mass of the second object divided by the distance between the two objects squared.

g is the local acceleration due to gravity between 2 objects. We get this value from the Law of Universal Gravitation. Force = m*a = G(M*m)/r^2. Here you use the radius of the earth for r, the distance to sea level from the centre of the earth, and M is the mass of the earth.
