Question

Use the exact values you enter to make later calculations.

    You repeat the same experiment that you did in the lab with the force table using two 100 g masses at 105 and 255.
             (a) Complete the table below.         

  

        (b) Determine (by calculation) the value of F3 needed to balance the two forces F1 and F2.
        F3x = .507 N
        F3y = ??? Why is this not 0?
        
                     

                                                                                                                                                        

Force Mass (kg) Magnitude of Force (N) Angle (degrees) Ax (N) Ay (N) F1 0.100 0.98 105 -.25 .9466 F2 0.100 0.98 255 -.25 -.9466

Explanation / Answer

here,

f3 = - (f1 + f2)

F3x = - (f1x + f2x)

F3x = - (-0.25 - 0.25)

F3x = 0.5 N

F3y = - (f1y + f2y)

F3y = - (0.9466 - 0.9466)

F3y = 0

magnitude of F3 is 0.5 N

the angle with the +ve x axis be theta

theta = arctan(0/0.5)

theta = 0 degree

the direction is 0 degree counter clockwise from the +ve x axis
