(D) The gravitational force between the astronaut and the asteroid.
Reason :
All the other forces given in the options, except (D), doesn't account for the motion of the astronaut. They are the forces that act between nucleons or atoms and neither of them accounts for an objects motion.

Answer:
a
The x- and y-components of the total force exerted is
b
The magnitude of the force is
The direction of the force is
Clockwise from x-axis
Explanation:
From the question we are told that
The magnitude of the first charge is
The magnitude of the second charge is
The position of the second charge from the first one is
The magnitude of the third charge is
The position of the third charge from the first one is
The position of the third charge from the second one is
The force acting on the third charge due to the first and second charge is mathematically represented as
Substituting values
The magnitude of is mathematically evaluated as
The direction is obtained as
Forces that are equal in size but opposite in direction and do not cause a change in an object's movement are called balanced forces.
forces that aren't equal in size and do cause a change in movement (what it seems like you're asking for) are called UNBALANCED FORCES
so answer (in case that wasn't clear, as I'm tired) : unbalanced forces
