Answer:
option A
Explanation:
Earth density can be deduced with the help of gravitational pull and the volume.
gravitational pull of the earth is equal to= [tex]\dfrac{GM}{R^2}[/tex]........(1)
We know, the volume of the earth, with the help of that we can calculate radius of the earth.
We know gravitational pull on earth = 9.8 m/s²
From equation (1) we can calculate the mass.
So, Density = mass/ Volume.
From the above expression we can calculate the density of earth.
Hence, the correct answer is option A
