Answer:
exponential relation
Step-by-step explanation:
A lift force is a force that is exerted by a fluid which has its component in the perpendicular direction flow direction of the fluid.
The relationship between the lift force and the vesicle radius is best described by the exponential relationship.
In an exponential relationship, the slope between the lift force and the vesicle radius is very increasing at a very high rate. As the radius increases, the lift force increase at a higher rate.
