    A spring balance is attached to the ceiling of a lift. A man hangs his bag on the spring and the spring balance reads 49 N, when the lift is stationary. If the lift moves downward with an acceleration of 5 m/s25\ \text{m/s}^2, the reading of the spring balance will be (g=9.8 m/s2g=9.8\ \text{m/s}^2)
