Detailed Solution
Download Solution PDFअवधारणा:
किया गया कार्य: यह बल और विस्थापन का बिंदु गुणनफल है ।
किया गया कार्य (W) = बल (F) × विस्थापन (S)
बल द्वारा किया गया कार्य-
W = F × Δs =F-S आलेख के अधीन वक्र का क्षेत्रफल
गणना:
W =आलेख के अधीन वक्र का क्षेत्रफल
W1 (1m - 2m) = \(area~of~rectangle= base × height = 1 × 10 =10\)
W2 (2m - 3m) = 1 × 5 = 5
तो दूरी (x = 1m से x = 3m) को तय करने में किया कार्य = 10 + 5 = 15 जूल
इसलिए सही उत्तर विकल्प 2 है।
