Circus

How does the concept of balance in a circus relate to the center of mass in physics?

• The center of mass must be above the base of support for balance.

• The center of mass must be below the base of support for balance.

• The center of mass has no effect on balance.

• The center of mass must be at the edge of the base of support for balance.
