A person looking through a telescope T just sees the points on the rim at the bottom of a cylindrical vessel when the vessel is empty. When the vessel is completely filled with a liquid `(mu, = 1.5)`, he observes a mark at the centre B,of the bottom without moving the telescope or the vessel. What is the height of the vessel if the diameter of it scross section is 10cm.
