What is the mass of 4.2 kg of gold when it is transferred to a planet having twice the gravity of earth?

I believe I answered this elsewhere are well, but...

Weight and mass are two different things.

Mass is a measure of the amount of matter contained in something, weight is a measure of force (F-ma).

Doubling the gravity would certainly affect the weight, but do you think it would affect the mass?

8.4

To calculate the mass of an object on a different planet, you need to consider the effect of gravity. The weight of an object is determined by its mass and the gravitational force acting on it.

In this case, we know the mass of the gold is 4.2 kg. We need to find the mass of the gold on a planet with twice the gravity of Earth.

The formula to calculate weight is given by:

Weight = mass x gravity

On Earth, the gravity is approximately 9.8 m/s². Since the planet in question has twice the gravity of Earth, the gravity on that planet would be 2 times 9.8 m/s², which is 19.6 m/s².

To find the mass on the other planet, we can rearrange the formula:

Weight = mass x gravity

mass = Weight / gravity

Now, substitute the known values:

mass = 4.2 kg / 19.6 m/s²

Using a calculator, divide 4.2 by 19.6 to get the mass on the other planet.

Hence, the mass of 4.2 kg of gold on a planet with twice the gravity of Earth would be the result you calculated.

2 x 4.2 kg?
