2 Accuracy
3 Systematic error
4 Random error
PHXI02:UNITS AND MEASUREMENTS

367452 The true length of a wire is \(3.678\;cm\). When the length of this wire is measured using instrument \(A\), the length of the wire is \(3.5\;cm\). When the length of the wire is measured using instrument \(B\), it is found to have length \(3.38\;cm\). Then the

1 measurement with \(B\) is more accurate and precise.
2 measurement with \(A\) is more precise while measurement with \(B\) is more accurate.
3 measurement with \(A\) is more accurate and precise.
4 measurement with \(A\) is more accurate while measurement with \(B\) is more precise.
