Consider a problem in which a car of massmis on a road tilted at an angletheta. the normal forceselect the best answer. select the best answer. n=mgn=mg \cos(\theta)n=\frac{mg}{\cos(\theta )}is found using\sum \vec{f}=m \vec{a}

Explanation:

The attached figure shows that the car of mass m is placed at an angle θ on an inclined plane. The forces acting on it are the force of gravity, the frictional force and the normal.

The weight of the object will act in downward direction. the frictional force opposes the motion of the car and the normal force act in upward direction.

The weight of the car can be resolved in two rectangular components as shown in the attached figure.

So, the normal force acting on the box is,

So, the correct option is (b). Hence, this is the required solution.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
