A man is standing in a lift which goes up and comes down with the same constant acceleration. The ratio of the apparent weights in the two cases (up trip to down trip) is $3 : 2$ . The acceleration of the lift is: (Take $g = 10$ m/s²)

Options:

Answer:

Solution:

$\frac{g + a}{g - a} = \frac{3}{2}$
gives
$2 g + 2 a = 3 g - 3 a$
so
$a = \frac{g}{5} = 2 m/ s^{2} .$
Option A.
