The coefficient of static friction between a box and a ramp is 0.5. The ramp's incline angle is `30^(@)`. If the box is placed at rest on the ramp, the box will

In Fig. 6-37, a block of mass m = 5.0 kg is at rest on a ramp. The coefficient of static friction between the block and ramp is not known. Find the magnitude of the net force exerted by the ramp on the block.

The coefficient of static friction between the box and the train's floor is 0.2. The maximum acceleration of the train in which a box lying on its floor will remain stationary is ("Take g"=10ms^(-2))

The coefficient of static friction between the box and the train's floor is 0.2. The maximum acceleration of the train in which a box lying on its floor will remain stationary is ("Take g"=10ms^(-2))

A block rests on a rough inclined plane making an angle of 30° with the horizontal. The coefficient of static friction between the block and inclined plane is 0.8. If the frictional force on the block is 10 N, the mass of the block is

A box, heavier than you is placed on a rough floor. The coefficient of static friction between the box and the floor is the same as that between your shoes and the floor. Can you displace the box across.the floor.

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=10ms^(-1) . This maximum acceleration of the car, for the box to remain stationary, is

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 1 g=10" ms"^(-2) . The maximum acceleration of the car, for the box to remain stationary, is
