Answer
Remember that the net force on you determines how your motion changes. The strength of the gravitational force between two objects depends on two factors, mass and distance. The Mass of the Objects The more mass two objects have, the greater. the force of gravity the masses exert on each other.
Explanation:

I know. I know everything
Since rope is parallel to the inclined plane so here we can say that net force parallel to the person which is pulling upwards must counterbalance the component of weight of the person.
Now here we will do the components of the weight of the person
given that weight of the person = 500 N
now its components are
![W_x = 500 cos37](https://tex.z-dn.net/?f=W_x%20%3D%20500%20cos37)
![W_y = 500 sin37](https://tex.z-dn.net/?f=W_y%20%3D%20500%20sin37)
now here as we can say that one of the component is balanced here by the normal force perpendicular to plane
while the other component of the weight is balanced by the force applied on the rope
So here the force applied on the rope will be given as
![F = W_y = 500 sin37](https://tex.z-dn.net/?f=F%20%3D%20W_y%20%3D%20500%20sin37)
![F = 300 N](https://tex.z-dn.net/?f=F%20%3D%20300%20N)
so it apply 300 N force along the inclined plane
Answer:
In a two particle system, the center of mass lies on the center of the line joining the two particles.
