Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Question

this is ONE question, please answer both short parts. thank you.

Consider the straight rod as given below:
Rod
Pivot
The rod has a uniform mass density. We want to
place a pivot underneath the rod to balance it. Please
answer the following questions.

Where should we place the pivot such that the rod is
horizontally balanced?
At the middle
O At th of the length from the left of the rod
At th of the length from the right of the rod
none of the above
After placing the pivot, we place a mass m on edge
of the right arm of the rod, where m is less than the
mass of the rod. Where should we place the pivot
arm now to balance the rod?
Place it at the middle.
Place it somewhere between the middle and right edge.
Place it somewhere between the middle and left edge.
Place it on the right edge at the mass.
