A glass tube filled with Mercury is attached to the bottom of an iron pendulum rod of length 100 cm. How high must the Mercury be filled in the glass tube so that the centre of mass of this pendulum will not rise or fall with changes in temperature? Linear expansion coefficient of Iron = 11 x 106 K-1 and cubical expansion of coefficent of Mercury = 18.2 x 106 K-1
