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, 5.0N) I chose 4.0N but the correct answer is 0.5N. Can someone explain why my answer is wrong and why 0.5N is correct? Thanks in advance.
