Question

The center of gravity of an irregular object is shown in (see figure). You need to move the center of gravity 2.08 cm to the left by gluing on a tiny 1.37-g mass, which will then be considered as part of the object. Where should you attach this additional mass? (Take the mass of the irregular object to be 5.15 g. The origin is at the original center of gravity of the object, and +x is to the right.)

Explanation / Answer

xCM = m2x2/(m1+m2) *x2 -(m1+m2)/(m2)

Xcm = (5.15+1.37/1.37) -(2.08cm)

Xcm = -9.89 cm

additional mass must be attached at 9.89 cm to the left

xCM = m2x2/(m1+m2) *x2 -(m1+m2)/(m2)

Xcm = (5.15+1.37/1.37) -(2.08cm)

Xcm = -9.89 cm
