A metal cylinder, totally immersed in water, is hung from a newton meter. The cylinder, of height L, is slowly raised vertically by lifting the newton meter. As the base of the cylinder moves from line X in the water to line Y above the surface of the water, the reading R on the newton meter is recorded. The velocity of the cylinder is constant. Which graph best shows the variation of R with the distance d of the base of the cylinder from line X?
