Question

Symbolic objects constructed out of sticks of equal length and mass. The location of the centre of mass is described using the coordinate system depicted in the sample.

The centre of mass lies at x = 0, y = 0. Consider following symbols:

TestHub · Accepted Answer

Treat each stick as a point mass at its centre and combine the midpoints.

(P): symmetric about the x-axis with mass shifted right of the y-axis, so COM is at $x > 0, y = 0$ - (A) correct.

(T): symmetric about the origin, so COM is at $(0, 0)$ - (D) correct.

(R) has mass shifted left ( $x < 0$ ) and (S) is symmetric about the y-axis ( $x = 0$ ), so (B) and (C) fail.
