Represent the forces š¹1 = 3š ā š and š¹2 = 3š + 5š, on graph paper, showing both forces acting on an object at the point (0, 0). Complete the diagram to show the magnitude and direction of the resultant force š¹š .
Solution:
š¹1Ā = 3š ā š and š¹2Ā = 3š + 5š
š¹1Ā = ā š +3š and š¹2Ā = 3š + 5š
So, š¹1=(-1,3) and š¹2=(3,5).
Now, clear "F_R+F_1=F_2"
"F_R=F_2-F_1= 3 \\hat\ud835\udc56 + 5\\hat\ud835\udc57-(3\\hat\ud835\udc57 \u2212 \\hat\ud835\udc56 )=4\\hat i-2\\hat j"
