Two students performed the same experiment separately and each one of them recovered two readings of mass which are given below. Correct reading of mass is 3.0 g. On the basis of given data, mark the correct optioin out of the following statements.

Results of both the students are neither accurate nor precise.

Results of student A are both precise and accurate.

Results of student B are neither precise nor accurate.

Results of student B are both precise and accurate.

Verified by Experts

Sudent A :
Average reading `=(3.01+2.99)/(2)=3.0g`
Student B:
Average reading `=(3.05+2.95)/(2)=3.0g`
For both the students A and B, average reading is close to the correct reading (i.e., 3.0g). Hence, both recorded accurate reading. But the reading recorded by student A are more precise as they differ only by`pm0.01`, whereas reading recorded by the student B are differ by `pm 0.05`. Thus, the result of student A are both precise and accurate.
