the question (for seo and search engine optimization to get this question to the top)

Calculate the force of gravity on the 1-kg mass if it were 3.2×106m above Earth's surface (that is, if it were one and a half Earth radii from Earth's center).

F= 4.3N

Recuerda que la Ley de gravitación universal de Newton puede enunciarse así: “Toda partícula de

materia en el universo atrae a todas las demás partículas con una fuerza que es directamente

proporcional a las masas de las partículas e inversamente proporcional al cuadrado de la distancia que

las separa”. Ley que se puede expresar simbólicamente de la siguiente forma:

2

1 2

d

m m F ⋅ ∝

Podemos expresar la proporcionalidad de la ley de gravitación universal en forma de una ecuación

exacta introduciendo la constante de proporcionalidad G, llamada constante de gravitación universal:

1 2

m m F G ⋅ = ⋅ donde

0.19 m/s and 0.45 m/s

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
