A man is standing in a lift which goes up and comes down with the same constant acceleration. If the ratio of the apparent weights in the two cases is $2 : 1$ , then the acceleration of the lift is: (Take $g = 10$ m/s²)

Options:

Answer:

Solution:

$\frac{m ( g + a )}{m ( g - a )} = 2$
gives
$g + a = 2 g - 2 a$
so
$a = \frac{g}{3} = \frac{10}{3} = 3.33 m/ s^{2} .$
Option A.
