A satellite of mass $1000$kg is rotating around the earth in a circular orbit of radius $3$R. What extra energy should be given to this satellite if it is to be lifted into an orbit of radius $4R$?

Q. A satellite of mass $1000kg$ is rotating around the earth in a circular orbit of radius $3R$. What extra energy should be given to this satellite, if it is to be lifted into an orbit of radius $4R$?

Q. A satellite is moving in a circular orbit around the earth. The total energy of the satellite is $E=-2\times {10}^{5}J$. the amount of energy to be imparted to the satellite to transfer it to a circular orbit, where its potential energy is $U=-2\times {10}^{5}J,$ is

Q. A satellite of mass m is orbiting the earth in a circular orbit of radius $r$. It starts losing energy due to small air resistance at the rate of $CJ/s$. Then the time taken for the satellite to reach the earth is

Q. A satellite revolves around the Earth of radius $R$ in a circular orbit of radius $3R$. The percentage increase in energy required to lift it to an orbit of radius $5R$ is
