पाण्याच्या थेंबाविषयी पुढे सर्वसाधारण विधाने आहेत : (a) पाण्याच्या थेंबाचा आकार गोलाकार असण्यास पृष्ठताण कारणीभूत आहे. (b) गुरुत्वाकर्षण नसतानाही पाण्याच्या थेंबाचा आकार गोल असतो. (c) जर पाण्याचे वस्तुमान ताणले गेले तर थेंब तयार होतात. वरीलपैकी कोणते/कोणती विधान/विधाने बरोबर आहे/आहेत ?
(a)Surface tension is responsible for the spherical shape of the water drops.
(b)Even in the absence of gravitation, water drops have spherical shape.
(c)Formation of water drops occurs, if mass of the water is stretched.
Surface tension minimizes the surface area of a liquid, giving water drops a spherical shape. This holds true even without gravity, and stretching liquid masses results in droplet formation.
