An arm of a teapot is completely filled with tea (density=ρ) If the arm has a length of l and is inclined at 30^o to the horizontal, what will be the pressure difference between the two points, C at the mouth and D at the base of the arm?
(a) ρgl
(b) ρgl/2
(c) √2ρgl
(d) 2ρgl
I had been asked this question in an international level competition.
