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. A. Results of both the students are neither ac curate nor preciseB. Results of student A are both percies and accurateC. Results of student B are neither precise nor accurateD. Results of student B are both precise and accurate. |

Answer» Average of readings of student, `A=(3.01+2.99)/(2)=300` Average of readings of student ,B`=(3.05+2.95 )/(2)=300` Correct reading = 3.00 For both studnets average value is close to the correct value. Hence readings of both are accurate Readings of student A are close to each other (differ only by 0.02) and also close to the correct reading, of A are precise also. But readings of B are not close to each other (differ by 0.1) and hence are not precise. |
