8. Two forces of 40N and 80N act at an angle of 120 to each other. Find the magnitude and direction of the equilibrant force. (Include a diagram representing the forces) (5 marks 9. Determine the intersection (if any) of the following lines: F=(-8,-5,1)+(1,4,-1) and F = (3,0,5)+u(3,-1,2). (5 marks) 8. Two forces of 40N and 80N act at an angle of 120 to each other.
