A) $6.08 \times 10^{-44} \mathrm{~N}$
B) $6.08 \times 10-43 \mathrm{~N}$
C) $6.08 \times 10^{-45} \mathrm{~N}$
D) $6.08 \times 10^{-42} \mathrm{~N}$

The gravitational force can be calculated using Newton's law of universal gravitation: $F = G \frac{m_1 m_2}{r^2}$. Substituting the given values, $F = 6.67 \times 10^{-11} \frac{(3.20 \times 10^{-27})^2}{(1.06 \times 10^{-10})^2}$, yields $F = 6.08 \times 10^{-44} \mathrm{~N}$.
