Download Solution PDFसंकल्पना:
- स्थितिज ऊर्जा (PE): एक निकाय द्वारा अपनी स्थिति या विन्यास के आधार पर प्राप्त की गयी ऊर्जा को स्थितिज ऊर्जा कहा जाता है।
\(PE = mgh\)
जहां, m = निकाय का द्रव्यमान, g = गुरुत्वाकर्षण के कारण त्वरण और h = निकाय की ऊंचाई
गणना:
दिया हुआ है कि
द्रव्यमान = 12 kg
स्थितिज ऊर्जा (PE) = 600 J
गुरुत्वाकर्षण के कारण त्वरण (g) = 10 m/s-2
ऊँचाई = ?
हम जानते हैं कि, स्थितिज ऊर्जा = mgh
h = स्थितिज ऊर्जा/mg = 600/[12 × 10] = 5 m
इसलिए, ऊंचाई (h) = 5 m। तो विकल्प 1 सही है।
