Detailed Solution
Download Solution PDFसंकल्पना:
- कार्य: कार्य को एक बल द्वारा किया जाना तब कहा जाता है जब वस्तु वास्तव में लागू बल की दिशा में कुछ दूरी के तक विस्थापित होती है।
- चूँकि वस्तु F की दिशा में विस्थापित होती है इसलिए दूरी s से वस्तु को विस्थापित करने में बल द्वारा किया गया कार्य निम्न है
\(W = \vec F \cdot \vec s\)
- इसलिए बल द्वारा किया गया कार्य वस्तु के बल और विस्थापन के अदिश या डॉट गुणनफल के बराबर होता है।
व्याख्या:
दिया गया है,
द्रव्यमान = 25 kg
दूरी = 15 m
कार्य = 480 J
समीकरण का उपयोग करके:
\(Work = Force \times Distance\)
∴ 480 = \(F\times 15\)
F = \(480\over15\)= \(32\ N\)
बल = 32 N
