Physics · JEE | UNITS AND MEASUREMENT
हिन्दीGiven below are two statements: Statement I: A physical quantity can be measured with high precision yet still be inaccurate due to systematic errors. Statement II: The number of significant figures in a measurement depends upon the choice of units used to express it.
View Answer & Solution
Correct answer · Option C
Statement I is correct but Statement II is incorrect.
Explanation
Precision refers to the resolution of measurement, which can be high even with systematic shifts (inaccuracy). Statement II is false because a change of units does not change the number of significant digits in a measurement.
