Question

Some numbers and experimental data are given in list I and their significant figure are given in List II Match List I to List II

Answer 1

Solution

A) $1.732$ cm (measured by meter scale)

$\Rightarrow$ least count of metre scale is $0.1cm$ so, significant no. of $1.732cm$ is only

so, singnificant no. = 2.

B) $100$

$\Rightarrow$ Right side zero is not included in significant net number,

$\therefore$ significant no. $=1$

C) $4.70\times {10}^5$

${10}^c$ not inclded in significant no.

$\therefore$ Significant $no=3$

D) 1.674 ( least count $0.001cm$ )

B. least count is (0.001) $cm$

$\therefore$ Significant no. $=4$
