A force table is used to determine the resultant of two forces acting in the same plane. The table is set up as follows: - Force F₁ = 5.0 N directed along the 0° (horizontal) line. - Force F₂ = 3.0 N directed along the 90° line (perpendicular to F₁). - The resultant is measured with a spring balance attached to the string that represents the combined force. The reading on the balance is 8.0 N and the direction of the resultant string makes an angle of 31° with the 0° line. Answer the questions below.

Question Parts

( a )
Calculate the theoretical magnitude and direction of the resultant of F₁ and F₂ using vector addition.
( b )
Using the measured resultant (8.0 N at 31°), calculate the percentage error in the magnitude of the resultant.
( c )
Suggest two reasons why the measured resultant may differ from the theoretical value and briefly explain each.
