`K.E.` of an orbiting satellite is `K`. The minimum additional `K.E.` required so that it goes to infinity is

The K.E. of a satellite is 10^(4)J . It's P.E. is

The K.E. of a satellite is 2MJ. Its total energy is

The ratio of the K.E. required to the given to the satellite to escape earth's gravitational field to the K.E. required to be given so that the satellite moves in a circular orbit just above earth atmosphere is

The ratio of the K.E. required to the given to the satellite to escape earth's gravitational field to the K.E. required to be given so that the satellite moves in a circular orbit just above earth atmosphere is

A satellite is orbiting close to the earth and has a kinetic energy K. The minimum extra kinetic energy required by it to just overcome the gravitation pull of the earth is

A satellite is orbiting close to the earth and has a kinetic energy K. The minimum extra kinetic energy required by it to just overcome the gravitation pull of the earth is

In hydrogen atom radius of the first orbit is 0.53 Å . Minimum work required to free the electron, given its K.E in the orbit is half the magnitude of P.E in the orbit.
