Seven homogeneous bricks, each of length L, are arranged as shown in figure. Each brick is displaced with respect to the one in contact by L/10. Find the x-coordinate fo the centre of mass relative to the origin shown. Figure
Let OX be the X-axis and point O (0, 0) be the origin of the system.
The mass of each brick is M.
The length of each brick is L.
Each brick is displaced with respect to another in contact by a distance .
∴ The X-coordinate of the centre of mass is given as,
The X-coordinate of the centre of mass relative to the origin is .
