Question

The normal force acting upon the car is best represented by arrow __. The force of gravity acting upon the washers is best represented by arrow__. The applied force on the car is best represented by arrow __.

Answer 1

Answer:

The normal force acting upon the car is best represented by arrow A. The force of gravity acting upon the washers is best represented by arrow D. The applied force on the car is best represented by arrow C.

Explanation:

The normal force is the reaction force which acts in upward direction when object is in contact with another stable object. In the given figure, weight of car is acting downwards represented by B and normal force acting in the upward direction is represented by A.

The washer is hung from the pulley. The force of gravity always acts in the downward direction. It is represented by arrow D in the figure.

The applied force on the car is represented by arrow C towards right.

Answer 2

Answer:

1. The normal force acting upon the car is best represented by arrow A.    

Reason:

The direction of normal force is always upward and opposite to gravitational force that why A is correct option.

2. The force of gravity acting upon the washers is best represented by arrow B.

Reason:

The direction of gravitational force is always downward toward the center of gravity and opposite to normal force that why B is correct option.

3. The applied force on the car is best represented by arrow C.

Reason:

The direction of applied force is along the  direction in which it moves. that why C is correct option.
