A man “weighing 70 kg is coming down in a lift. If the cable of the lift breaks suddenly, the weight of the man would become

When the cable of a lift breaks, the lift and the person inside enter a state of free fall, accelerating downward at the acceleration due to gravity (g). In physics, weight is typically measured as the normal force exerted by a surface on an object. During free fall, both the man and the lift accelerate at the same rate, meaning there is no contact force or normal force between the man's feet and the floor of the lift. Consequently, the apparent weight, which is what a scale would register, becomes zero. This phenomenon is known as weightlessness. While the man's mass remains 70 kg, the force he exerts on the lift floor vanishes because both are falling together under gravity's influence. Therefore, the reading on any weighing device would be zero.
