Which of the following devices works on Archimedes’ principle?
निम्नलिखित में से कौन-सा उपकरण, आर्किमिडीज के सिद्धांत पर कार्य करता है?
Detailed Solution & Logic
Hydrometer/ उत्प्लव-घनत्वमापी
📘 Explanation
Archimedes’ Principle :
A body immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by it.
A hydrometer works based on this principle.
-
A hydrometer is used to measure the density or relative density of liquids.
-
When placed in a liquid, it floats.
-
The depth to which it sinks depends on the liquid’s density.
-
In a denser liquid, it floats higher.
-
In a less dense liquid, it sinks deeper.
-
This floating behavior occurs due to the buoyant force, explained by Archimedes’ principle.
📗 व्याख्या
आर्किमिडीज का सिद्धांत :
किसी द्रव में डूबी वस्तु पर ऊपर की ओर लगने वाला उत्प्लावन बल, विस्थापित द्रव के भार के बराबर होता है।
हाइड्रोमीटर (उत्प्लव-घनत्वमापी) इसी सिद्धांत पर कार्य करता है।
-
इसका उपयोग द्रव का घनत्व या सापेक्ष घनत्व मापने के लिए किया जाता है।
-
इसे द्रव में रखने पर यह तैरता है।
-
यह कितना डूबेगा, यह द्रव के घनत्व पर निर्भर करता है।
-
अधिक घनत्व वाले द्रव में ऊपर तैरता है।
-
कम घनत्व वाले द्रव में अधिक डूबता है।
-
यह उत्प्लावन बल आर्किमिडीज के सिद्धांत के कारण होता है।
⭐ Extra Facts / अतिरिक्त तथ्य
🔹 English
-
Hydrometers are used in battery testing, milk testing, and alcohol industries.
-
Ships float on water due to Archimedes’ principle.
🔹 Hindi
-
हाइड्रोमीटर का उपयोग बैटरी, दूध और अल्कोहल उद्योग में किया जाता है।
-
जहाज का पानी पर तैरना भी आर्किमिडीज सिद्धांत का उदाहरण है।
