PhysicsEasysingle choice

Maximum acceleration of the train in which a $50 kg$ box lying on its floor will remain stationary (Given, coefficient of static friction between the box and the train's floor is $0.3 a n d g = 10 m s^{- 2}$ )

Options:

Answer:

Solution:

box remain stationary when $m a \leq μ m g$

$\Rightarrow a \leq μ_{s} g$

Here, $μ_{s} = 0.3, g = 10 m s^{- 2}$

$a \leq (0.3) \times 10$

$\Rightarrow a \leq 3 m s^{- 2}$
