Assume that the average mass of each of the approximately 1 billion people in China is 55 kg. Assume that they all gather in one place and climb to the top of 2 m high ladders. The center of mass of the Earth (m_E = 5.90 10²⁴ kg) is then displaced

Question

Quizplus · Accepted Answer

The displacement of the center of mass can be calculated using the formula: Δx = (Mtotal/m_E) * h, where Mtotal is the total mass of the people and h is the height they climb to. Mtotal = (1 billion) * (55 kg/person) = 5.5 × 10^10 kg Δx = (5.5 × 10^10 kg / 5.90 × 10^24 kg) * 2 m = 1.84 × 10^-14 m This is closest to option C, 1.84 × 10^-14 m.
