Locate ,the centre of mass of the uniform then L-shaped body as shown

1.	Locate ,the centre of mass of the uniform then L-shaped body as shown in Fig. Assume its thickness to be t and density rho.
Answer» SOLUTION :With respect to ORIGIN the C.M. of the rectangle A is `x_(A)=1.0 m` `y_(A) = 0.10` m and that of the rectangle B is `x_(B) = (1.80 + 0.10) = 1.90 m`, `y_(B)=-0.74 m, m_(A) =2 XX 0.2 xx trho = 0.4 rho tm^(2), m_(B) = 1.48 xx 0.2 xx rhot = -0.26 rho tm^(2)` `x_( cm) = m_(A)x_(A) + m_(B)x_(B)//m_(A) + m_(B) = 0.4 rho t xx 1 + 0.26 rhoxx 1.9//0.4 rhot+ 0.26 rhot = 1.35 m`
