A box of mass is placed on the roof of a car. The box would remain stationary until the car attains a maximum acceleration. The coefficient of static friction between the box and the roof of the car is and . The maximum acceleration of the car, for the box to remain stationary, is
Step 1. Given data
Mass of the body,
The coefficient of static friction,
Step 2. Finding the maximum acceleration,
For the box to remain stationary, the applied force, is equal to the frictional force,
Hence, the correct option is .
