$A$ man inside an artificial satellite feels weightlessness because the force of attraction due to the Earth is

Why can the entire surface of the Earth be viewed with the help of a polar satellite?

The gravitational potential energy required to raise a satellite of mass $m$ to a height $h$ above the Earth's surface is $E_1$. Let the energy required to put this satellite into orbit at the same height be $E_2$. If $M$ and $R$ are the mass and radius of the Earth respectively,then the ratio $E_1: E_2$ is:

The motion of planets in the solar system is governed by which of the following conservation laws?

Which of the following is the evidence to show that there must be a force acting on the Earth and directed towards the Sun?
