Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFअवधारणा:
गतिज ऊर्जा (KE):
- निकाय द्वारा अपनी गति के आधार पर धारण की जाने वाली ऊर्जा को गतिज ऊर्जा कहा जाता है।
- गतिज ऊर्जा के लिए अभिव्यक्ति है
\(KE = \frac{1}{2}m{v^2}\)
जहाँ m = निकाय का द्रव्यमान और v = निकाय का वेग
गणना:
दिया गया है,
द्रव्यमान (m)= 1 किलोग्राम
वेग (v)= 10 m/s
गतिज ऊर्जा के सूत्र का प्रयोग करने पर,
गतिज ऊर्जा = \({1 \over 2}\times {m \times v^2}\)
\(Kinetic Energy= {1\over2}\times{1 \times 10^2}={100\over2}=50 J\)
∴वस्तु की गतिज ऊर्जा 50 J है।
∴ सही विकल्प चौथा है।
