Hey student.
 
The tidal effect depends inversely on the cube of the distance, while the gravitational force depends on the square of the distance.

Which of the following symptoms is likely to afflict an astronaut in space (a) swollen feet, (b) swollen face, (c) headache, (d) orientational problem?

Hey student.
 

(b), (c), and (d)

(a) Legs hold the entire mass of a body in standing position due to gravitational pull. In space, an astronaut feels weightlessness because of the absence of gravity. Therefore, swollen feet of an astronaut do not affect him/her in space.

(b) A swollen face is caused generally because of apparent weightlessness in space. Sense organs such as eyes, ears nose, and mouth constitute a person's face. This symptom can affect an astronaut in space.

(c) Headaches are caused because of mental strain. It can affect the working of an astronaut in space.

(d) Space has different orientations. Therefore, orientational problem can affect an astronaut in space.

 

This is the answer to your question. Hope this helps you.

(i) When the person is at centre of earth.
(ii) When the person is at the null points in space (at these points the gravitational forces due to different masses cancel each other)
(iii) when a person is standing in a freely falling lift.
(iv) When a person is inside a space craft which is orbiting around the earth.
 
This is the answer to your question. Hope this helps you.
