Static friction is a force that keeps object at rest. It must be overcome to start moving the object.
Factors on which the static firctional force depends:
1) Force exerted by the body on the surface.
2) Contact surface if they were rough, then friction between their surface is more and vice versa.

Answer:
The y component of the force is 2 N.
Explanation:
It is given that,
Force acting on the object, F = 4 N
Angle with the x- axis,
We need to find the y component of the force. The x and y components of the force is as follows :
So, the y component of the force is 2 newton. Hence, this is the required solution.

An object is said to be in a rectilinear motion when two objects are moving in a straight line and are parallel to each other. Elevator movement is an example of rectilinear motion
There are three types of rectilinear motion, and they are uniform rectilinear motion, uniformly accelerated rectilinear motion and rectilinear movement with non-uniform acceleration
