Statement I: Droplets of liquid are usually more spherical in shape than large drops of the same liquid. Statement II: Force of surface tension predominates force of gravity in case of small drops.

Small droplets of a liquid are usually more spherical in shape than larger drops of the same liquid because

Surface tension is the property of a liquid by virtue of which the free space of the liquid at rest tends to have minimum area and as such it behaves as if covered with a stretched membrane. It is measured as the force acting an unit length of a line imagined to be drawn tangentially anywhere on the free surface of liquid at rest. It acts at right angles to this line on both sides and along the tangent to the liquid surface. Raindrops are spherical in shape because each drop tends to acquire maximum surface area : (a) True (b) False
