Gravitational Force Practice Test

In a laboratory on Earth, a student measures the mass of a block to be $$m_g$$ using a spring scale and $$m_i$$ using an inertial balance. The experiment is then moved to a spaceship accelerating at $$a=g$$ in deep space. How will the new measurements, $$m'_g$$ and $$m'_i$$, compare to the original measurements?

An object of mass $$m$$ is placed inside a uniform solid sphere of mass $$M$$ and radius $$R$$ at a distance $$r$$ from its center, where $$r < R$$. The magnitude of the gravitational force on the object is proportional to which of the following quantities?
