Question

Please answer d,e,f,g

A planet of mass \(5 \times 10^{24}\) kg is at location \((5 \times 10^{11}, -5 \times 10^{11}, 0)\) m. A star of mass \(5 \times 10^{30}\) kg is at location \((-6 \times 10^{11}, 5 \times 10^{11}, 0)\) m. It will be useful to draw a diagram of the situation, including the relevant vectors.

(a) What is the relative position vector \(\mathbf{\hat{r}}\) pointing from the planet to the star?
\[
\mathbf{\hat{r}} = \langle -1.1 \times 10^{12}, 1.1 \times 10^{12}, 0 \rangle \, \text{m}
\]

(b) What is the distance between the planet and the star?
\[
|\mathbf{\hat{r}}| = 14.866 \, \text{m}
\]

(c) What is the unit vector \(\mathbf{\hat{r}}\) in the direction of \(\mathbf{\hat{r}}\)?
\[
\mathbf{\hat{r}} = \langle -.74, -.67, 0 \rangle
\]

(d) What is the magnitude of the force exerted on the planet by the star?
\[
|F_{\text{on planet}}| = 7.56e42 \, \text{N}
\]

(e) What is the magnitude of the force exerted on the star by the planet?
\[
|F_{\text{on star}}| = \, \text{N}
\]

(f) What is the force (vector) exerted on the planet by the star? (Note the change in units.)
\[
\mathbf{F}_{\text{on planet}} = \, \times 10^{20} \, \text{N}
\]

(g) What is the force (vector) exerted on the star by the planet? (Note the change in units.)
\[
\mathbf{F}_{\text{on star}} = \, \times 10^{20} \, \text{N}
\]
