7. Consider a planet that is assumed to be a solid sphere with a core of mass Mc = 4, 13 x 10²4 kg and radius R₂ = 6,17 x 106 m. The core is surrounded by an outer shell of thickness 1,8Rc and mass 3,3M, as shown in the diagram given below. (The diagram is not to scale.) I I *+ --- 1,8R Re 15 If a particle is h = 2,4R, above the surface of the planet, then (rounded to two decimal places) the gravitational acceleration ||a9|| of this particle is equal to: (a) 0,61 m/s²
