If a pendulum were placed over a large iron ore deposit under the Earths surface, what change would be observed in its period?
A.The period of the pendulum would be shorter, because the density of the iron ore beneath it would slightly increase the fraction of its acceleration that is due to gravity.
</SPAN>B. The period of the pendulum would be longer, because the density of the iron ore beneath it would slightly decrease the fraction of its acceleration that is due to gravity.
</SPAN>
Answer: A
How would I know this?
