Option 4 is the best option

Step-by-step explanation:

I just did it on E2020

Answer 2

Answer: Image for option 4

Step-by-step explanation:

The fourth option is correct because there are three forces acting on the block:

`F_(f)` which is the Friction force and acts against the movement of the block

`F_(N)` the Normal Force, which is perpendicular (normal) to the surface of the rough ramp

`F_(g)` the Weight of the block, which is the force due gravity acceleration and has an x-component and an y-component.
