Question 128

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A particle of mass 8 kg hangs in equilibrium under the action of three forces: its weight, a force of magnitude P P\,P newtons acting at 30° 30°\,30° above the horizontal, and a force of magnitude Q Q\,Q newtons acting at 60° 60°\,60° above the horizontal on the opposite side of the vertical.

a.

Find the value of P P\,P and the value of QQQ.

[6]
b.

Show that the two applied forces are perpendicular, and verify your answers to part (a) using this fact.
