How can I find the net force of this and the direction ?
Thanks.

you need to know some additional info: the angle between the vectors.

and given that you need to show some work before we can help you.

It's just an example for me to understand something, but I didn't know that it missed some additional info sorry, lol.
Let's suppose that the angle is 45 degree.
