The normal reaction on a body placed in a lift moving up with constant acceleration $2 m s^{- 1}$ is $120 N$ . Mass of the body is (Take $g = 10 m s^{- 2}$ )

Options:

Answer:

Solution:

From force diagram shown in figure,

$N - m g = m a_{0}$

or $120 - m g = 2 m$

$∴ m = \frac{120}{g + 2} = \frac{120}{10 + 2}$

$= 10$ kg
