measurement with $A$ is more accurate while measurement with $B$ is more precise.

Vedclass · Answer

(B) Given,true length of wire $l_0 = 3.678 \,cm$.Measurement with instrument $A$ is $l_A = 3.5 \,cm$.Measurement with instrument $B$ is $l_B = 3.38 \,cm$.Accuracy is determined by how close the measured value is to the true value. The absolute error for $A$ is $|3.678 - 3.5| = 0.178 \,cm$,and for $B$ is $|3.678 - 3.38| = 0.298 \,cm$. Since $0.178  Precision is determined by the resolution or the number of decimal places of the instrument. Instrument $A$ measures up to one decimal place,whereas instrument $B$ measures up to two decimal places. Therefore,instrument $B$ is more precise.

The true length of a wire is $3.678 \,cm$. When the length of this wire is measured using instrument $A$,the length is $3.5 \,cm$. When the length of the wire is measured using instrument $B$,it is found to be $3.38 \,cm$. Then,the:
