Question

the acceleration due to gravity at a height h in terms of mass of earth Me radius of earth is Re and gravitational constant G is​

Answer 1

Answer:

Gravity is the force that pulls a body towards the earth's centre. Consider the masses ma and mb of two bodies. When two bodies are subjected to equal forces,

Explanation:

• The above mass is referred to as a body's gravitational mass. The inertial mass and gravitational mass are same, according to the principle of equivalence. This will be used to calculate acceleration due to gravity, as seen below.
• Assume a body [test mass (m)] is dropped from a height 'h' above the earth's surface [source mass (M)], it begins to travel downhill with increasing velocity as it approaches the earth's surface.
• We know that an object's velocity changes only when it is subjected to a force, which in this case is gravity.
• Under the gravitational influence on two bodies,  
• FA = GMmA/r2,
• FB = GMmB/r2,
• mB = [FB/FA] × mA
