A balloon and a mass are attached to a rod that is pivoted at a fixed point P. The balloon is filled with helium, which is a gas that is less dense than air. The balloon filled with helium applies an upward force on the rod. The rod is horizontal and in equilibrium. Which action causes the rod to rotate clockwise?

• moving the balloon to the 40cm mark and the mass to the 30cm mark

• moving the balloon to the 20cm mark and the mass to the 10cm mark

• moving the balloon to the 25cm mark and the mass to the 25cm mark

• moving the balloon to the 20cm mark and the mass to the 30cm mark
