Vedclass · Answer

(C) When a small spherical ball is dropped into a viscous liquid,it initially accelerates due to gravity. As its velocity increases,the viscous drag force (which is proportional to velocity) also increases. Eventually,the net force becomes zero when the viscous drag and buoyant force balance the weight of the ball. At this point,the ball attains a constant velocity known as the terminal velocity. In the given graph,the $y$-axis represents velocity and the $x$-axis represents distance. As the ball falls,its velocity increases initially and then levels off to a constant value as it approaches terminal velocity. Curve $C$ shows the velocity increasing and then becoming constant with respect to distance,which correctly represents the motion of the ball in a viscous liquid.
