At one end
At the top
At a random point
At the midpoint of its axis

Question 2747

▼

Why is the center of mass of a homogeneous rod at its midpoint?

Because it is longer at one end
Because gravity pulls more at the center
Because the ends are thicker
Because of symmetry about the center

Question 2748
