The coordinates of centre of mass of a uniform flag shaped lamina

(2)

For given Lamina

                  $x y$

$(1.5,2.5)$

$m_{1}=1, C_{1}=$

$m_{2}=3, C_{2}=$ $(0.5,1.5)$

$X_{c m}=\frac{m_{1} x_{1}+m_{2} x_{2}}{m_{1}+m_{2}}=\frac{1.5+1.5}{4}=0.75$

$Y_{c m}=\frac{m_{1} y_{1}+m_{2} y_{2}}{m_{1}+m_{2}}=\frac{2.5+4.5}{4}=1.75$

$\therefore$ Coordinate of centre of mass of flag shaped lamina

$(0.75,1.75)$
