NEET2010PhysicsMotion in One DimensionActual

Assertion : The apparent weight of a body in an elevator moving with some downward acceleration is less than the actual weight of a body. Reason : The part of the weight is spent in producing downward acceleration, when body is in elevator.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion

Step-by-step solution

The apparent weight of a body in an elevator moving with downward acceleration a is given by W=m(g-a)
