Question

Assertion (A): Apparent weight of an astronaut in artificial earth satellite is zero.
Reason (R) : Earth gravitational force on the astronaut is almost zero.

• A. Both A and R are true and R is correct explanation of A
• B. Both A and R are true and R is not correct explanation of A
• C. A is true and R is false
• D. A is false and R is true

Answer 1

Answer: (C)

A is true and R is false

Apparent weight of an astronaut in an artificial earth satellite is zero, because weight of the astronaut is balanced by the centrifugal force, which is produced due to revolution.
Earth's gravitational forces on the astronaut is not zero as the gravitational force is universal and always act on astronaut.
