Calculate Gravitational Force Mathematically Practice Test

Earth and the Sun are separated by about $r = 1.5 \times 10^{11}\ \text{m}$ (center to center). Use $M_E = 6.0 \times 10^{24}\ \text{kg}$, $M_{\text{Sun}} = 2.0 \times 10^{30}\ \text{kg}$, and $G = 6.67 \times 10^{-11}\ \text{N}\cdot\text{m}^2/\text{kg}^2$. What is the magnitude of the gravitational force between Earth and the Sun?

A $60\ \text{kg}$ 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 $F = G\dfrac{M_E m}{R_E^2}$?
