Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The correct choice is B.
Because the centripetal force equals the gravitational force exerted by the earth on the spaceship, the astronaut does not experience any gravitational force of the earth. The only force of gravity that an astronaut in an orbiting spaceship experiences is that which is due to the gravitational force exerted by the spaceship. Since the spaceship is massive, this force os finite but very small.
