Read this paragraph and choose the correct option from the provided answers:

A space station was established far from the gravitational field of Earth. Extended stays in zero gravity are not healthy for human beings. Thus, for the comfort of the astronauts, the station is rotated so that the astronauts feel there is an internal gravity. The rotation speed is such that the apparent acceleration of gravity is . The direction of rotation is counter-clockwise. If the radius of the station is , what is its rotational speed, ?.

 Choices:

- revealed gravity

- still gravity

- Fixed Gravity

- internal gravity


A:
internal gravity
