The terminal velocity of ball of radius R inside a liquid of viscosity η can be written as VT=n2R2g(σ−ρ), where σ is the density of ball and δ is the density of the liquid.Hence,A is correct since VT∝R2 gives a parabola on a graphC is correct since VTαη1 and η varies with temperatureD is correct since VTα(σ−ρ) i.e., varies with density of liquid.
