A)
F = 0.0626 N

B)
F = 0.0313 N

C)
F = -0.0626 N

D)
F = -0.0313 N

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x, y components step 4 step 5 step 6
