Question

the acc diue to gravity on the surface of the earth is 10m/s² the average density of the planet if twice that the average density of the earth and the radius of the planet is the half of that of the radius of the planet. an astronaut weighing 50kg on the earth. how much will hw weigh on this planet

Answer 1

The weight of the astronaut on the planet is 500 N.

Step-by-step explanation:

The weight of an object on a planet depends on the acceleration due to gravity on that planet.

In this case, the acceleration due to gravity on the surface of the planet is given as 10 m/s², while on Earth it is 9.8 m/s².

Since weight is proportional to the acceleration due to gravity, we can calculate the weight of the astronaut on the planet using the formula:

Weight on planet = Mass x Acceleration due to gravity on planet

Given that the astronaut's weight on Earth is 50 kg, we can substitute the values into the formula to get:

Weight on planet = 50 kg x 10 m/s²

= 500 N
