A box of mass 
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 \(g=10 \mathrm{~ms}^{-2} .\)
The maximum acceleration of the car, for the box to remain stationary, is
