Question

Calculate the density of Earth from Newton’s law of
gravitation

Vipra Mishra · Accepted Answer

Dear Student Assuming earth to be a perfect sphere of radius R and uniform density p, mass of Earth=volume of Earth x density,

The average radius of the Earth is 6 38 x 106 meters The universal gravitational constant G is Nm2/s2 The acceleration of gravity at the surface of the Earth is about

Substitute the values we will get p =3×9 84×3 14×6 67 x 10-11×6 38×106
