Question

Derive an expression for the mass of earth. Also, calculate the value of mass of earth.

Answer 1

Answer:

Explanation:

The mass of the Earth may be determined using Newton's law of gravitation. It is given as the force (F), which is equal to the Gravitational constant multiplied by the mass of the planet and the mass of the object, divided by the square of the radius of the planet

Answer 2

Answer:

we have, g = (GM)/(r^2)

where,

g = acc. due to gravity

G = gravitational constant

M = mass of earth

r = radius of earth

we can calculate mass of earth via this as,

M = (g)(r^2)/G
