A rocket has to be launched from earh in such a way that it never returns. If E is the minimum energy delivered by the rocket launcher what should be the minimum energy that the launcher should have if the same rocket has launcher from the surface of the moon ? Assume that the density of the earth and the moon are equal and that the earth's volume is 64 times the volume of the moon

The distnace of the moon from the earth is about 60 times the radius of the earth. What will be diameter of the earth (approximately in degrees) as see from the moon?

The radius of the moon is 1//4 th the radius of the earth and its mass is 1//80 th the mass of the earth. Calculate the value of g on the surface of the moon.

The moon's distance from the earth is 360000 km and its diameter subtends an angle of 31' at the eye of the observer. Find the diameter of the moon.

The acceleration due to gravity on the moon is only one sixth that of earth.It the earth and moon are assume to have the same density, the ratio of the radii of moon and earth will be

If the moon attracts the earth, why does the earth not move towards the moon?

The ratio of the radius of the earth to that of the motion is 10. the ratio of the acceleration due to gravity on the earth to that on the moon is 6. The ratio of the escape velocity from the earth's surface to that from the moon is
