If both assertion and reason are true and reason is the correct explanation of assertion

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

If assertion is true but reason is false

If both assertion and reason are false

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