It the earth was half its mass, then it might only be able to hold half the atmosphere. In this case, it may not be able to maintain many species of life as we know it.

What is the value of gravitational field strength on a planet with half Earth's mass and half its radius?

The value of the gravitational field strength on a planet with half the mass and half the radius of Earth would be the same as Earth's gravitational field strength. This is because the gravitational field strength depends only on the mass of the planet and the distance from the center, not on the size or density of the planet.


If the Earth shrunk to half its size what happens to Earth's original mass?

Assuming the earth is a sphere, it corresponds to the rule that M is proportional to radius^3 - shrinking the radius by half, we see: (1/2)^3 = 1/8, the earth has shrunk to a mere eighth of it's mass.

Why is the mass of an object the same on the moon as it is on earth but the objects weight is different?

That is because Earth has more gravity. Weight = mass x gravity.


Why is the gravity different to on the moon than on earth?

The strength of gravity of an object is proportional to its mass. The moon has much less mass than earth does.
