Question

Assertion :In a free fall, weight of a body becomes effectively zero. Reason: Acceleration due to gravity acting on a body having free fall is zero.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

The true weight--the gravitational force that the earth exerts on the object--remains. What is zero is the apparent weight, which is the magnitude of the contact force supporting an object. That's what is meant by the term "weightless"--the apparent weight is zero, not the "true" weight. When standing on the ground, both your true and apparent weight equal mg. When you jump off the roof, your true weight is mg while your apparent weight goes to zero
