Which force is responsible for the necessary centripetal force of a satellite revolving around the Earth?

An astronaut orbiting the Earth in a circular orbit $120 \ km$ above the surface of the Earth,gently drops a spoon out of the spaceship. The spoon will

Given below are two statements:
Statement $I$: $A$ satellite is moving around the Earth in an orbit very close to the Earth's surface. The time period of revolution of the satellite depends upon the density of the Earth.
Statement $II$: The time period of revolution of the satellite is $T = 2\pi\sqrt{\frac{R_e}{g}}$ (for a satellite very close to the Earth's surface),where $R_e$ is the radius of the Earth and $g$ is the acceleration due to gravity.
In the light of the above statements,choose the correct answer from the options given below:

Consider a satellite going round the Earth in an orbit. Which of the following statements is wrong?

$A$ satellite is orbiting just above the surface of the earth with period $T$. If $d$ is the density of the earth and $G$ is the universal constant of gravitation,the quantity $\frac{3 \pi}{G d}$ represents :

$A$ person sitting in a chair in a satellite feels weightless because
