A person weighing 785 Newtons on the surface of the Earth would weigh 47 Newtons on the surface of Pluto. What is the magnitude of the gravitational acceleration on the surface of Pluto?

3.72 N / kg .

Explanation:

The weight of the object can be calculated using the expression below

Weight = mg

Weight= 785 Newtons

M = mass

g= acceleration due to gravity on Earth is 9.8 m/s² .

So, substitute the values we have,

So on Earth . . .

785 N = m x 9.8

mass= 785/9.8

=80.1kg

We can calculate when on On Mars, as

Weight= mg

298N= 80.1 kg x g( on Mars)

Acceleration of gravity of that Mars =

298 N/ 80.1

= 3.72 N / kg .

Hence, the magnitude of the gravitational acceleration on the surface of Pluto is 3.72 N / kg .
