Directions: There are two statements, one labeled the Assertion (A) and the other labeled the Reason (R). Examine the statements and decide if the Assertion A and Reason R are individually true and if so, whether the reason is the correct explanation of the assertion. Select your answers to the question from the codes given below:

Assertion (A): Objects appear 'weightless' inside an orbiting spacecraft. Reason (R): Objects in circular motion experience centripetal force.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are true but R is not the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true

Explanation

Assertion A is true because astronauts are in free fall. Reason R is true because objects in orbit are indeed experiencing centripetal force, but this force is not the cause of weightlessness; rather, the lack of a normal force is.
