हिन्दीThe true mass of an object is \( 2.00\text{ g} \). Three students perform two measurements each and obtain the following results: Student A: \( 1.95\text{ g} \), \( 1.93\text{ g} \) Student B: \( 1.94\text{ g} \), \( 2.05\text{ g} \) Student C: \( 2.01\text{ g} \), \( 1.99\text{ g} \) Which student's data is both precise and accurate?
Correct answer · Option 3
Student C
Explanation
Student C's readings (\( 2.01\text{ g} \) and \( 1.99\text{ g} \)) are close to each other (precise) and their average is \( 2.00\text{ g} \), which matches the true value (accurate).
