Hemisphere

A beam of diameter 'd' is incident on a glass hemisphere as shown in the figure. If the radius of curvature of the hemisphere is very large in comparision to d, then the diameter of the beam at the base of the hemisphere will be:

Two solid hemispheres of radii R and (R )/(2) with centers O and O' respectively as shown in figure. The density of bigger hemisphere is rho and that of smaller hemisphere is 2rho . Taking center of bigger hemisphere is at origin and the distance between centres of two hemisphere OO' is (R)/(10) find co - ordinates of center of mass of the system.
