A box of mass $2 kg$ is placed on the roof of a car. The box would remain stationary until the car attains a maximum acceleration. Coefficient of static friction between the box and the roof of the car is 0.2 and $g = 10 ms^{- 2}$ This maximum acceleration of the car, for the box to remain stationary, is

Options:

Answer:

Solution:

Given, $m = 2 kg, μ = 0.2$ and $g = 10 ms^{- 2}$ Here, $ma = μ m g$ $a = μg a = 0.2 \times 10 a = 2 m / s^{2}$
