If the coefficient of friction between an object and an inclined plane is 0.2, and the angle of inclination is 30°, what is the force of friction on the object?

Ff=0.2mgF_f = 0.2mgFf=0.2mg

Ff=0.2mgcos⁡(30∘)F_f = 0.2mg \cos(30^\circ)Ff=0.2mgcos(30∘)

Ff=0.2mgsin⁡(30∘)F_f = 0.2mg \sin(30^\circ)Ff=0.2mgsin(30∘)

Ff=μmgcos⁡(30∘)F_f = \mu mg \cos(30^\circ)Ff=μmgcos(30∘)

Correct! Wrong!

Which of the following is the correct expression for the component of gravitational force parallel to the inclined plane?

F∥=mgcos⁡θF_{\parallel} = mg \cos \thetaF∥=mgcosθ

F∥=mgsin⁡θF_{\parallel} = mg \sin \thetaF∥=mgsinθ

F∥=mgF_{\parallel} = mgF∥=mg

Correct! Wrong!

If an object is sliding down an inclined plane with friction, what forces act on the object?

Only gravitational force

Only frictional force

Gravitational force and normal force

Gravitational force, normal force, and frictional force

Correct! Wrong!

Which of the following will increase the acceleration of an object sliding down an inclined plane?

Increasing the mass of the object

Decreasing the angle of the incline

Increasing the coefficient of friction

Increasing the angle of the incline

Correct! Wrong!

In the case of an object on an inclined plane with no friction, what determines the acceleration of the object?

The mass of the object

The angle of inclination of the plane

The gravitational force only

The coefficient of friction

Correct! Wrong!

What is the force acting on an object placed on an inclined plane?

Only normal force

Only gravitational force

Gravitational force and normal force

Gravitational force and frictional force

Correct! Wrong!

At what angle of inclination will the object start to slide down the incline if the coefficient of static friction is μs\mu_sμs?

θ=tan⁡−1(μs)\theta = \tan^{-1}(\mu_s)θ=tan−1(μs)

θ=μs\theta = \mu_sθ=μs

θ=sin⁡−1(μs)\theta = \sin^{-1}(\mu_s)θ=sin−1(μs)

θ=cos⁡−1(μs)\theta = \cos^{-1}(\mu_s)θ=cos−1(μs)

Correct! Wrong!

What is the effect of the angle of inclination on the normal force?

The normal force increases as the angle increases

The normal force decreases as the angle increases

The normal force remains the same regardless of the angle

The normal force becomes zero at all angles

Correct! Wrong!
