4. (a) Two solutions contain two different colloids (I and II)

4. (a) Two solutions contain two different colloids (I and II) suspended in two different fluids (1 and 2, respectively). If fluid 1 and fluid 2 have the same viscosity but colloid II is twice the diameter of colloid I, what is the ratio of diffusion coefficients, Di/D2? (b) Make a sketch of the MSD vs. time for each colloid on the same linear scale of distance and time. 4.
