Units and Measurements MCQ questions with answers
The first 3 of 19 questions. Unlock the series for the rest, each with a solution.
Q1. Consider the following rules regarding significant figures. 1. All non-zero digits are significant. 2. Trailing zeros in a number with no decimal point are always significant. 3. Zeros appearing between two non-zero digits are significant. Which of these statements is/are correct?
सार्थक अंकों के संबंध में निम्नलिखित नियमों पर विचार कीजिए। 1. सभी अशून्य अंक सार्थक होते हैं। 2. दशमलव बिंदु रहित संख्या में पश्चगामी शून्य सदैव सार्थक होते हैं। 3. दो अशून्य अंकों के बीच आने वाले शून्य सार्थक होते हैं। इनमें से कौन-सा/से कथन सही है/हैं?
- A. 1 and 2 only / केवल 1 और 2
- B. 1, 2 and 3 / 1, 2 और 3
- C. 1 and 3 only / केवल 1 और 3
- D. 2 and 3 only / केवल 2 और 3
Solution
Statements 1 and 3 are standard rules. Statement 2 is wrong: trailing zeros in a number without a decimal point are ambiguous and generally not treated as significant.
कथन 1 और 3 मानक नियम हैं। कथन 2 गलत है: दशमलव बिंदु रहित संख्या में पश्चगामी शून्य अस्पष्ट होते हैं तथा सामान्यतः सार्थक नहीं माने जाते।
Q2. Which of the following is NOT an SI base unit?
निम्नलिखित में से कौन-सा SI आधारी मात्रक नहीं है?
- A. Newton / न्यूटन
- B. Candela / कैंडेला
- C. Mole / मोल
- D. Kelvin / केल्विन
Solution
The candela, mole and kelvin are among the seven SI base units, whereas the newton is a derived unit (kg·m·s⁻²).
कैंडेला, मोल तथा केल्विन सात SI आधारी मात्रकों में से हैं, जबकि न्यूटन एक व्युत्पन्न मात्रक है (kg·m·s⁻²)।
Q3. Which of the following pairs of physical quantities have the same dimensional formula?
निम्नलिखित में से किस भौतिक राशियों के युग्म का विमीय सूत्र समान है?
- A. Force and surface tension / बल और पृष्ठ तनाव
- B. Pressure and energy density / दाब और ऊर्जा घनत्व
- C. Work and power / कार्य और शक्ति
- D. Impulse and force / आवेग और बल
Solution
Both pressure and energy density have the dimensions [ML⁻¹T⁻²]. The other pairs do not match in dimensions.
दाब तथा ऊर्जा घनत्व दोनों की विमाएँ [ML⁻¹T⁻²] हैं। शेष युग्मों की विमाएँ मेल नहीं खातीं।
