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

The ratio of the radius of the earth to that of moon is 10 . The ratio of acceleration due to gravity on the earth and on the moon is 6 . What is the ratio (in intergral value) of the escape velocity from the earth's surface to that from the moon?

The mass of the earth is 81 times that of the moon and the radius of the earth is 3.5 times that of the moon. The ratio of the escape velocity on the surface of earth to that on the surface of moon will be

The ratio of the mass of the moon to that of the earth is 1:81. If the radius of the moon is assumed to be one-fourth of that of the earth , then what is the acceleration due to gravity on the surface of the moon in terms of that on the earth's surface ? Hence, find the escape velocity from the surface of the moon in terms of that from the earth's surface.

What is the value of escape velocity from the surface of (/) earth, (//) moon?

The mass of the earth is 81 times that of the moon and the radius of the earth is 3.5 times that of the moon. The ratio of the acceleration due to gravity at the surface of the moon to that at the surface of the earth is

The radius and acceleration due to gravity of the moon are 1/4 and 1/5 that of the earth, the ratio of the mass of the earth to mass of the moon is

If the radius of the earth be 6.38 x10^(4) m and the acceleration due to gravity at earth be 9.8 ms^^(2) then calculate the escape velocity of a body from the earth.s surface.
