# The apparent weight of an object increases in an elevator while accelerating upward. A moongphaliwala sells his moongphali using a beam balance in an elevator. Will he gain more if the elevator is accelerating up?

Consider his weight is mass m and acceleration due to gravity is g [that is acting downwards]. Now according to Newton’s third law of motion "every action has an equal and opposite reaction". Therefore, there will be a reaction in the opposite side.

As we know Net force on a body is equal to mass × acceleration of the body.
Therefore

Hence when a lift accelerates upward there will be increase in weight
