I need help with f and g

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, 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? = (-8e + 11,ge + 11,0) E (b) What is the distance between the planet and the star? Irl = 1.2e+12 m (c) What is the unit vector r in the direction of ? (-0.667,0.75,0) (d) What is the magnitude of the force exerted on the planet by the star? IFon planet! = 4.16e+20 I Z (e) What is the magnitude of the force exerted on the star by the planet? IFon starl = 4.16e+20 Z (f) What is the force ( vector) exerted on the planet by the star? (Note the change in units.) Fon planet = (-1.9e + 20,2.2e + 20,0) x 1020 N X (g) What is the force (vector) exerted on the star by the planet? (Note the change in units.) Fon star = (1.9e + 20, - 2.2e + 20,0) x 1020 N X Additional Materials
