The mass of a body measured by a physical balance in a lift at rest is found to be $m$. If the lift is going up with an acceleration $a$, its mass will be measured as
The mass of a body measured by a physical balance in a lift at rest is found to be $m$. If the lift is going up with an acceleration $a$, its mass will be measured as
$m\left( {1 - \frac{a}{g}} \right)$
$m\left( {1 + \frac{a}{g}} \right)$

Mass measured by physical balance remains unaffected due to variation in acceleration due to gravity.
