###### Assume a water strider has a roughly circular foot of radius $0.02 \mathrm{mm}$. (a) What is the maximum possible upward force on the foot due to surface tension of the water? (b) What is the maximum mass of this water strider so that it can keep from breaking through the water surface? The strider has six legs.
