A metal cylinder, fully submerged in water, is suspended from a newton meter. The cylinder has height $L$ and is lifted slowly upwards by raising the newton meter. As the cylinder’s base travels from line X in the water to line Y above the water surface, the reading $R$ on the newton meter is noted. The cylinder moves at constant speed. Which graph most accurately represents how $R$ changes with the distance $d$ of the cylinder’s base from line X?
