Physics

The mass of an object is measured by two students (true weight is 12 kg)
Student 1: He measures 12 kg
Student 2: She measures 12.5 kg
Measurement of which student is more accurate.


ANSWER

Student 1


SOLUTION
Accuracy defines nearness of a measured value to the standard or true value. Since value measured by student 1 is nearer to the actual value $$12 \ kg$$ compared to that measured by student 2. So measurement of student 1 is more accurate.
