Text SolutionText solutionverified iconVerified

(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, the orientational problems can affect an astronaut in space.
So, the correct option will be

Directions Assertion-Reason type. Each of these contains two Statements : Statement I (Assertion), Statement II (Reason). Each of these questions also has four alternative choices, only one of which is correct. You have to select the correct choices from the codes Assertion When distance between two bodies is doubled and mass of each body is also doubled. Gravitational force between them remains the same. Reason According to Newton's law of gravitation, force is directly proportional to mass of bodies and inversely proportional to distance between them.
  1. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion
  2. If both Assertion and Reason are true but Reason is not correct explanation of the Assertion

Example 5.1 An astronaut accidentally gets separated out of his small spaceship accelerating in inter stellar space at a constant rate of 100 m s2. What is the acceleration of the astronaut the instant after he is outside the spaceship? (Assume that there are no nearby stars to exert gravitational force on him.) Answer Since there are no nearby stars to exert gravitational force on him and the small spaceship exerts negligible gravitational attraction on him, the net force acting on the the spaceship, is parameter that determine on its motion.
