The forces acting on this object are _______ and the net force is ________
1 answer:
The forces acting on this object are Balanced and the net force is 0 N, the correct option is option (a).
A system is said to be balanced, when the resultant of the forces acting on the system is 0.
The resultant of the forces acting in a bi-direction is calculated as
R=
The force in x direction is Fx=+5-5=0
The force in x direction is Fy=+2-2=0
Therefore resultant force on the system is 0 N.

Answer:
g = 4.7 × m/
Explanation:
Given that the mass of the satellite = 700 kg, and 10,000 m above the earth;s surface.
From Newton's second law,
F = mg ............... 1
From Newton's gravitation law,
F = .................. 2
Where: F is the force, G is the gravitational constant, M is the mass of the first body, m is the mass of the second body, g is the gravitational force and r is the distance between the centers of the two bodies.
Equate 1 and 2 to have,
mg =
⇒ g =
But; G = 6.67 × N
, M = 700 Kg, r = 10000 m
Thus,
g =
=
= 4.669 × m/
The force of gravity on the satellite is 4.7 × m/
