Problem

A body loses the same fraction of its weight when taken to a depth

d

below the Earth’s surface as it does when raised to an altitude of

600\,\text{km}

above the surface. Neglect rotational effects. Which value is closest to

d

? a)

6.0 \times 10^{2}\,\text{km}

1.6 \times 10^{3}\,\text{km}

1.2 \times 10^{3}\,\text{km}

3.0 \times 10^{2}\,\text{km}
