Suppose an alien civilization has a space station in circular orbit around its home planet. The station’s orbital radius is twice the planet’s radius, (a) If an alien astronaut has weight w just before launch from the surface, will she be weightless when she reaches the station and floats inside of it? (b) If not, what will be the ratio of her weight in orbit to her weight on the planet’s surface?

a)

To determine
Whether the alien be weightless when it reaches the space station and floats inside it.

Explanation

Given info: The space station is in a circular orbit around the home planet. The station’s orbital radius is twice the planet’s radius.

Explanation:

The weight of the alien is given by,

w=mg
