Question 1

The center of mass of a system lies at the geometric center of the object.

True
False

💡 Hint: Consider cases where mass is unevenly distributed.

Question 2

What formula is used to calculate the center of mass for three particles?

X_{CM} = (m1*x1 + m2*x2 + m3*x3)/(m1 + m2 + m3)
X_{CM} = (m1 + m2 + m3)/(x1 + x2 + x3)
X_{CM} = (x1 + x2 + x3)/(3)
X_{CM} = m1*x1 + m2*x2 + m3*x3

💡 Hint: Think of how to balance masses.
