5. [5/7 Points] DETAILS PREVIOUS ANSWERS MI4 3.2.013. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A planet of mass 3 x 1024 kg is at location (4 x 1011, 4 x 1011, 0) m. A star of mass 3 x 1030 kg is at location (4 x 1011, 5 x 1011, O) m. It will be useful to draw a diagram of the situation, including the relevant vectors. (a) What is the relative position vector r pointing from the planet to the star? 2: m W (b) What is the distance between the planet and the star? |7| = 1.2e+12 y m (c) What is the unit vector ? in the direction of r? ; = (d) What is the magnitude of the force exerted on the planet by the star? a IFon planetI (e) What is the magnitude of the force exertec IFon starI = (f) What is the force (vector) exerted on the p s. Fon planet = (9) What is the force (vector) exerted on the star by the planet? (Note the change in units.) v = 4.16e+20 y N 4.16e+20 y N (71.9e + 20,2.2e + 2070) a Fon star = (1.9e + 20, 2.2e + 20,0) Additional Materials on the star by the planet? anet by the star?
