Answer:
327.894 N
Explanation:
We have given two forces Jhon pushes with a force of 185 N in east direction and Joan pushes with a force of 165 N at 30° north of east which is clearly shown in figure
We fave to find the total horizontal force
So total horizontal force will be 
=327.894 N ( total horizontal force will be sum of force in the east direction and horizontal component of the force in north- east direction)
F = G Mm/r²
mg = G Mm/r²
g = GM/r²
At centre of earth, r=0
g = GM/0
g =0
