11. In an experiment to determine the size of an oil molecule, clean water was placed in a large basin and then left over several minutes without any disturbance. Lycopodium powder was carefully
spread on the water surface. A drop of oil was then taken from a container using a fine wire. its
diameter was measured using a millimeter scale with the aid of a hand lens and was found to be
0.35mm. The oil drop was carefully transferred onto the water surface where it spread to form a
circular patch of diameter 14cm.
