Suppose you landed on an unknown planet whose mass is 10x that of the Earth and whose radius is 3x that of the Earth. How much would you weigh on this new planet?
Give your answer in what fraction or multiple of your earthly weight.



Answer :

Mass on the planet would be 10/3 times the mass on Earth weigh on this new planet.

How do you define mass?

A quantitative measure of the fundamental characteristic of all matter, inertia. In essence, it's the resistance of a mass of matter to changing its direction or speed in reaction to the force applied to it. The much more weight a body has, the less change an applied force produces.

Briefing:

Let the mass of Earth = Me

Let the radius of Earth = Re

Mass of the planet, Mp = 10Me

Radius of the planet, Rp = 3Re

Weight on other planet, W = ?

Weight on planets is determined by the gravitational force

Gravitational force, F = GMm/r²

where, G = gravitational constant

M = Mass of the planet

m = our mass

r = radius of the planet

Gravitational force on Earth:

F = G X Me X ma/ Re².....eq (1) (ma = mass on earth)

Gravitational force on planet :

F = G X 10Me X mₓ/ (3Re)²....eq (2) (mx = mass on other planet)

Dividing both the equations, we get

mx = 10/3ma

Therefore, mass on the planet would be 10/3 times the mass on Earth.
