Question

ABCDE is a regular pentagon with its center of gravity at O. What will be the most probable position (W, X, Y, Z or O) of the new center of gravity:

1. if a piece of clay is attached at point A?
2. if the pentagon is cut along the line PQ? (Of the remaining part DCBQPE)

Answer 1

1. If a piece of clay is attached at point A, the most probable position of the new center of gravity is X.
2. If the pentagon is cut along the line PQ (of the remaining part DCBQPE), the most probable position of the new center of gravity is Z.
