# Finding the Center of Mass of a Rod

Not what you're looking for?

A 3.0 kg rod of length 5.0 m has at opposite ends point masses of 4.0 kg and 6.0 kg(a) Will the center of mass of this system be (1) nearer to the 4.0 kg mass, (2) nearer to the 6.0 kg mass, or (3) at the center of the rod? Why?
(b) Where is the center of mass of the system?

##### Solution Summary

The solution gives the correct answer to the questions concerning the center of mass for a rod system and then explains how to get it in concise, logical steps.

##### Solution Preview

The correct answer is (2), i.e., the center of mass will be near the 6.0 kg mass.

Because, center of mass is the point where the net mass acts, numerically it is given as,
r_cm = sum(mi*ri)/sum(mi)

where i = 1 to n, mi ...
