You are a member of this channel, let me expatiate on my explanation. When the arrow(vector) is pointing to the right then it is positive but when pointing the left it is negative, when facing upward it's positive and when facing downward it is negative
Well-done sir
Thank you
Can we find the F first and substitute the value for F
Instead of writing Fcos45° we substitute the value for F
That is the procedure to find F
But this is very complex, is there another method that would be more easier
Okay
Why -Fcos 45 and not +Fcos 45, but it was located on the right side, and right side is positive
I said it in the video, watch patiently
