The moon revolves around the earth in a circular orbit of radius - `3.84xx10^5` km with velocity 1 km/s. The additional velocity required to escape from influencing earth satellite is

A satellite has to revolve round the earth in a circular orbit of radius 8 xx 10^(3) km. The velocity of projection of the satellite in this orbit will be -

The moon takes about 27.3 days to revolve around the earth in a nearly circular orbit of radius 3.84xx10^5 km . Calculate the mass of the earth from these data.

The moon takes about 27.3 days to revolve around the earth in a nearly circular orbit of radius 3.84xx10^5 km . Calculate the mass of the earth from these data.

A satellite revolving around a planet has orbit velocity 10km/s . The additional velocity required for the satellite to escape from the gravitational field of the planet is

Assuming that the moon moves around the earth in a circular orbit of radius 3.8xx10^5 km in 27 days and the earth moves around the sun in a circular orbit of radius of radius 1.5xx10^8 km in 365 days, find the ratio of the masses of the sun and the earth.

An artificial satellite revolves around the earth in a circular orbit and is at a height of 300 km above the surface of the earth. Find the orbital speed and the time period of the satellite. The radius of the earth=6400 km, g=980 cm*s^(-2) .

A satellite is revolving round the earth in a circular orbit with a velocity of 8km/s. at a height where acceleration due to gravity is 8m//s^(2) . How high is the satellite from the earth ? (Take R = 6000 km)
