Correct answer: D. 50 %
Explanation
The Richter scale is logarithmic: a rise of one magnitude unit means about 10 times the recorded wave amplitude, and roughly 31.6 (10^1.5) times the energy released. Because the question asks specifically about energy and no option gives about 31.6 times, NTA cancelled this question and awarded marks to all candidates; among the given choices only "10 times" reflects the tenfold Richter step.रिक्टर स्केल लघुगणकीय है: परिमाण में एक इकाई की वृद्धि का अर्थ है तरंग आयाम का लगभग 10 गुना होना तथा मोचित ऊर्जा का लगभग 31.6 (10^1.5) गुना होना। चूँकि प्रश्न विशेष रूप से ऊर्जा के विषय में है और लगभग 31.6 गुना वाला कोई विकल्प नहीं है, NTA ने इस प्रश्न को रद्द कर सभी अभ्यर्थियों को अंक दे दिए; दिए गए विकल्पों में केवल "10 गुना" रिक्टर स्केल के दस-गुने चरण को दर्शाता है।More People, Development and Environment questions
