Question

find the position vector of center of mass of each of the following systems​

Answer 1

Ans-

An extended object (made up of many objects) has a defined position vector called the center of mass. The center of mass can be thought of, loosely, as the average location of the total mass of the object.

Answer 2

Explanation:

$Position \: of \: center \: of \: mass x |cm = \frac{m |1|x |1| + m |2|x |2| }{m |1 | + m |2| } \\ Let the origin to the position of m |1|  i.e.  x |1| = 0 \\ x |2| = l \\ x |cm| = \frac{0 + m |2|l }{m |1| + m |2| } = \frac{m |2| l}{m |1| + m |2| }$
