SUMMARY
A space traveler weighing 500 N on Earth will weigh approximately 111.11 N on a planet with a radius three times that of Earth and a mass twice that of Earth. The calculation utilizes the formula for gravitational force, F = G(m1 * m2) / r^2, where G is the gravitational constant, m1 is the mass of the traveler, m2 is the mass of the planet, and r is the radius of the planet. The increased radius decreases the weight due to the inverse square relationship, while the increased mass increases the weight, resulting in a net decrease in weight on the new planet.
