Three identical spheres, each of mass $1\ kg$ are placed touching each other with their centres on a straight line. Their centres are marked $K, L$ and $M$ respectively. The distance of centre of mass of the system from $K$ is
Three particles of masses $1\,kg,\,\frac {3}{2}\,kg$ , and $2\,kg$ are located at the vertices of an equilateral triangle of side $a$ . The $x, y$ coordinates of the centre of mass are
Define centre of mass.
A small disc of radius $2\, cm$ is cut from a disc of radius $6\, cm$. If the distance between their centres is $3.2\, cm$, what is the shift in the centre of mass of the disc ....... $cm$.
A uniform rectangular thin sheet $ABCD$ of mass $M$ has length $a$ and breadth $b$, as shown in the figure. If the shaded portion $HBGO$ is cut off, the coordinates of the centre of mass of the remaining portion will be
