Assertion A An astronaut inside a massive spaceship orbiting around the earth will experience a finite but small gravitational force. Reason R The centripetal force necessary to keep the spaceship in orbit around the earth is provided by the gravitational force between the earth and the spaceship.

Options

  1. ABoth (A) and (R) are true and (R) is the correct explanation of (A)
  2. BBoth (A) and (R) are true and (R) is not the correct explanation of (A)
  3. C(A) is true but (R) is not true
  4. D(A) is not true but (R) is true

Correct answer

D. (A) is not true but (R) is true

Step-by-step solution

Astronaut would not experience any gravitational force as it is balanced by centrifugal force. So, A is false and R is true.
