What is the relation between the period of revolution of a satellite (revolving close to the earth surface) and the density of the earth?

The diameter of a planet is four times that of the earth. Find the time period of a pendulum on the planet, if it is a second pendulum on the earth. Take the mean density of the planet equal to that of the earth,

Calculate the radius of the earth if the density of the earth is equal to the density of the nucleus. [mass of earth 5.97xx10^(24) kg].
