A planet of mass 5 x 1024 kg is at location (5 x 1011, -5 x 1011, o) m. A star of mass 5 x 1030 kg is at location (-6 x 1011, 5 x 1011, 0) 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?
i= <-1.1-1012,1 -1012,0 >
(b) What is the distance between the planet and the star?
Ir| = 14.86e11
(c) What is the unit vector r in the direction of r?
7 = <-.74,.67,0 >
(d) What is the magnitude of the force exerted on the planet by the star?
|Fon planetl = 7.56e42
