8 N up
b
4 N left
c
0 N
d
8 N right

Answer 1

To find the net force on the object, we need to consider the individual forces acting on the object and their directions.

The given forces on the object are:
- A 4 N force acting to the right (positive x-direction)
- An 8 N force acting upwards (positive y-direction)
- A 4 N force acting to the left (negative x-direction)
- An 8 N force acting to the right (positive x-direction)

The net force is the vector sum of these forces. We can represent the forces on a coordinate system as follows:

8 N | C

------------------->
4 N B 4 N

From the diagram, we can see that the 8 N force upwards (in the positive y-direction) and the 4 N force to the left (in the negative x-direction) cancel each other out.

The only remaining forces are the 4 N force to the right (in the positive x-direction) and the 8 N force to the right (in the positive x-direction). Since they are acting in the same direction, we can simply add them together:

4 N + 8 N = 12 N

So, the net force on the object is 12 N to the right.
