In the arrangement shown, by what acceleration the boy must go up so that $100 kg$ block remains stationary on the wedge. The wedge is fixed and friction is absent everywhere. (Take $g = 10 m s^{- 2}$ )

Options:

Answer:

Solution:

For block to be stationary $T = 800 N$
If man moves up by acceleration $a$

$T - m g = m a$

$800 - 500 = 50 a$ ,

$a = 6 m s^{- 2}$
