K, so I dont quite understand how I find a persons weight on a different planet using the said person's weight, the mass of the other planet, and the radius of the planet?(adsbygoogle = window.adsbygoogle || []).push({});

So, for example:

Max weighs 1000 N on Earth. What would his weight be on a planet with twice the mass of Earth, but with the same radius?

How would I go about answering this and similar questions? Thanks for your help!!
