1.	A small spherical body of radius r made of material of density rho is dropped into a long column of viscous liquid of density sigmad and coefficient of viscosity eta.The graph of the terminal velocity (v) vs radius (r ) of the body will be
Answer» STRAIGHT line parabola ellipse none of these Solution :We KNOW, terminal velocity , `v=2/9(r^2(rho-sigma)g)/(ETA)` As `v PROP r^2` the GRAPH `v-r` is parabola.
