Question

a meter stick has a mass of 0.150 kg and balances at its center. when a small chain is suspended from one end, the balance point moves 29.0 cm toward the end with the chain. determine the mass of the chain in grams. your answer:

Answer 1

The mass of the chain is 75 grams.

Step-by-step explanation:

To determine the mass of the chain, we can use the principle of torque balance. When the chain is suspended from one end, the balance point of the meter stick moves towards the end with the chain. We can use the equation for torque balance:

Torque of the meter stick = Torque of the chain

Since the meter stick balances at its center, the torque of the meter stick is zero. Therefore, the torque of the chain is also zero:

Mass of the chain × Distance to the chain = Mass of the meter stick × Distance to the center

Substituting the given values, we have:

Mass of the chain × 29.0 cm = 0.150 kg × 14.5 cm

Solving for the mass of the chain:

Mass of the chain = (0.150 kg × 14.5 cm) ÷ 29.0 cm

Mass of the chain = 0.075 kg or 75 grams
