Question

(B) In statement $(b)$, the percentage error for $1 \ m$ length is $\frac{0.01}{1} 	imes 100 = 1 \%$. For $0.5 \ m$ length, the percentage error is $

Vedclass · Accepted Answer

Length of $1 \ m$ and $0.5 \ m$ have been both measured with the same absolute error of $0.01 \ m$. Both the measurements are equally accurate.

Vedclass · Answer

(B) In statement $(b)$, the percentage error for $1 \ m$ length is $\frac{0.01}{1} 	imes 100 = 1 \%$. For $0.5 \ m$ length, the percentage error is $\frac{0.01}{0.5} 	imes 100 = 2 \%$. Since the percentage error is different, the measurements are not equally accurate. Thus, statement $(b)$ is incorrect. In statement $(c)$, the number of significant digits in $1.6$ is $2$ and in $0.60$ is $2$ (leading zeros are not significant). Thus, statement $(c)$ is incorrect. In statement $(d)$, according to rounding rules, if the digit to be dropped is $5$, the preceding digit remains unchanged if even. Thus, $2.445$ rounded to two decimal places is $2.44$. Thus, statement $(d)$ is incorrect. Note: This question contains multiple incorrect statements $(b, c, d)$.
