Q.61
ICAR AIEEA PG 2024 - Physical Science
Statement Based +4 −1
English हिन्दी

Given below are two statements

Statement (I) : The capacitance method measures soil moisture content by analyzing changes in electrical capacitance, offering precise numerical readings due to its direct correlation with moisture levels.
Statement (II) : The finger-licking method estimates soil moisture content based on tactile sensations, yielding subjective numerical values prone to individual interpretation biases.

In light of the above statements, choose the most appropriate answer from the options given below:

नीचे दो कथन दिए गए हैं

कथन (I) : कैपेसिटेंस (धारिता) विधि विद्युत धारिता में परिवर्तनों का विश्लेषण करके मृदा नमी की मात्रा को मापती है, जो नमी के स्तर के साथ इसके सीधे सहसंबंध के कारण सटीक संख्यात्मक रीडिंग प्रदान करती है।
कथन (II) : फिंगर-लिकिंग (स्पर्श/अनुभव) विधि स्पर्श संवेदनाओं के आधार पर मृदा नमी की मात्रा का अनुमान लगाती है, जिससे व्यक्तिपरक संख्यात्मक मान प्राप्त होते हैं जो व्यक्तिगत व्याख्या पूर्वाग्रहों से ग्रस्त होते हैं।

उपर्युक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सबसे उपयुक्त उत्तर चुनें:
