Problem

A rocket exhaust gas stream exerts a force

\vec{F}_{g\to p}=3\,\hat{i}-4\,\hat{j}+12\,\hat{k}\,\text{N}

on the space probe (axes are fixed to the probe). What is the force that the probe exerts on the exhaust gas stream? a)

-3\,\hat{i}-4\,\hat{j}+12\,\hat{k}\,\text{N}

-3\,\hat{i}+4\,\hat{j}-12\,\hat{k}\,\text{N}

3\,\hat{i}-4\,\hat{j}+12\,\hat{k}\,\text{N}

-6\,\hat{i}+8\,\hat{j}-24\,\hat{k}\,\text{N}
