An astronaut on a spacewalk accidentally drops a tool, and it floats away. which of the following objects is exerting a gravitational force on the floating tool? choose all that apply the astronaut the moon the earth the sun

Gravitational force is given as

so here gravitational force will be given by above formula where the force between two objects depends on the mass of two objects and distance between them.

Now here since the tool is at finite distance from Astronaut and Moon, Sun, Earth

So all the above will exert gravitational force on the tool but the magnitude of force will be different as all of the above are of different masses and situated at different distance.

So all options are correct here

The Astronaut

The Moon

The Sun

The Earth

it has to be b, about 97 percent.
