relevant vectors. (a) What is the relative position vector $$\vec{r}$$ pointing from the planet to the star? $$\vec{r}=$$ $${?}^m$$ (b) What is the distance between the planet and the star? $$?\vec{r}?=\mathrm{m}$$ (c) What is the unit vector $$\hat{r}$$ in the direction of $$\vec{r}$$ ? $$\hat{r}=$$ (d) What is the magnitude of the force exerted on the planet by the star? $$\left|{\vec{F}}_{\text{on planet }}\right|=$$ $$\mathrm{N}$$ (e) What is the magnitude of the force exerted on the star by the planet? $$\left|{\vec{F}}_{\text{on star }}\right|=$$ $$\mathrm{N}$$ (f) What is the force (vector) exerted on the planet by the star? (Note the change in units.) $${\vec{F}}_{\text{on planet }}=\times 10^{20}\mathrm{N}$$ (g) What is the force (vector) exerted on the star by the planet? (Note the change in units.) $${\vec{F}}_{\text{on star }}=\times 10^{20}\mathrm{N}$$
