Vedclass · Answer

(A) According to the rules of significant figures,for a number less than $1$,the zeros to the right of the decimal point and to the left of the first non-zero digit are not significant.In the number $0.00764$,the zeros before the digit $7$ are not significant.Therefore,the significant figures are $7, 6,$ and $4$,which makes a total of $3$ significant figures.Thus,both Assertion $(A)$ and Reason $(R)$ are true,and $(R)$ is the correct explanation of $(A)$.

Assertion $(A)$: The number $0.00764$ has three significant figures.
Reason $(R)$: If the number is less than $1$,the zeros on the right of the decimal point but to the left of the first non-zero digit are not significant.
