# Are gravitational waves involved?

Let the gravitation field of part 1 be 1000 units and that of part 2 be E. Let the plane make an angle $$60 ^ \circ$$ with the vertical plane. Find $$\lfloor E \rfloor$$.

Clarifications:

• $$AB$$ is one of the diameter and is in the horizontal plane.

• The dotted line other than $$AB$$ denotes the vertical plane.

• The figure is a solid hemisphere.
