A body of mass $50 kg$ is suspended using a spring balance inside a lift at rest. If the lift starts falling freely, the reading of the spring balance is

Options:

Answer:

Solution:

Given,

Mass of the body, $m = 50 k g$

When lift is moving down,

Scale reading $= \frac{m (g - a)}{g}$

If lift starts falling freely, then

$a = g$

Now, scale reading $= \frac{m (g - g)}{g} = 0$
