The figure shows composite shape comprising of two long slender rod bodies. The horizontal body has a length of 1.2m and mass 3kg; the second body has a length 0.4m and mass 1kg. The centre of gravity of each of the individual bodies can be found at their geometric centre, labelled G₁ and G2₂ in the figure. The composite shape has symmetry about the x axis, thus its centre of gravity lies on the line 'y=0' as depicted in the figure. Calculate the x coordinate of the centre of gravity of the composite shape. O O 0.95 m 0.75 m 0.50 m Don't Know 0.60 m G₁ G₂

A solid consists of a cylinder and a hemisphere of equal radius fixed base to base. Find theratio of the radius to the height of the cylinder, so that the solid has its centre of gravity atthe common face. Hint. For stable equilibrium, the centre of the body should be below the common face ormaximum lie on it. So take the centre of gravity of the body at a distance (a) from thebottom of the hemisphere.
