A composite rod whose upper half has a density `(rho)/(4)` and lower half has a density of `(3rho)/(2)` is immersed vertically in a liquid of density `rho`. To what length it shoul be immeresed so that centre of buoyancy coincides with centr of mass of the rod ? suppose the length is `(x l)/(14)` Find `x` .  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/RES_P06_17_MPCT_P7_XI_E01_029_Q01.png" width="80%"
