question 1b



Homework Equations





The Attempt at a Solution


I drew a triangle using a scale of 1cm=1N. I drew (at least I think I did) a decent sketch with the help of the protractor and ruler. For the resultant length i Just connected the two ends of the 8N and 6N lengths(which gave me a triangle). I measured the resultant which gave me 5.1cm, which with my scale is 5.1N. But my answers way off. Am i doing it right?

You connected the wrong points. Make a parallelogram of the vectors, and show your drawing.

Kk i used a parallelogram this time, and got 13N thanks.
