ANSWER

$F\text{ becomes }\frac{1}{4}\text{ as large}$ . Force varies as $\frac{1}{r^2}$ , so $(2r)^2=4$ in denominator.

60\ \text{kg}

astronaut is on Earth's surface. Using

M_E = 6.0 \times 10^{24}\ \text{kg}

R_E = 6.4 \times 10^{6}\ \text{m}

, and

G = 6.67 \times 10^{-11}\ \text{N}\cdot\text{m}^2/\text{kg}^2

, what is the gravitational force on the astronaut according to

F = G\dfrac{M_E m}{R_E^2}
