4) the mass of pluto is 1.31 x 1022 kg and its radius is 1.15 x 106 m. what is the acceleration of
a freely-falling object at the surface of pluto if it has no atmosphere? (g= 6.67 * 10-11 n.
m2/kg2)

Gravity is a universal force of attraction that exists between all the objects having mass and energy. The gravity is directly proportional to mass and has an inverse relationship with radius.

The acceleration of a freely-falling object on Pluto is 0.661 m/s².

Given:

Mass of Pluto = 1.31×10²² kg

Radius of Pluto = 1.15×10⁶ m

Gravitational constant = 6.67×10⁻¹¹ m³/kg/s²

Formula for the gravitational force:

Substituting the values in the above formula:

g = 0.661 m/s².

Therefore, the acceleration of a free-falling object will be 0.661 m/s².

0.661 m/s²

Explanation:

g = MG / r²

g = (1.31×10²² kg) (6.67×10⁻¹¹ m³/kg/s²) / (1.15×10⁶ m)²

g = 6.61×10⁻¹ m/s²

g = 0.661 m/s²
