Hello Rory, for the question the forces can act anywhere. Thus I don't think Pythagoras theorem can be used since the vectors need not form a right angle.

Hello John, thanks for the reply. I still don't understand why 0.5N cannot be a possible net force. Can't the resultant arrow be small if you have the opposite angle small as well? I don't understand how the other force of 3.0N can act to achieve 4.0N only. Where would it act upon?I hope you...

Hello everyone. :) I encountered this question during my revision and can't remember how I got it correct. "A force of 3.0N and a force of 4.0N act on an object at the same time. Which of the forces cannot be the resultant force on the object?" There are 4 options (0.5N, 3.5N, 4.0N...
