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.
- A Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\).
- B Both \((A)\) and \((R)\) are true but \((R)\) is not the correct explanation of \((A)\).
- C \((A)\) is true but \((R)\) is false.
- D (A) is false but \((R)\) is true.
Answer & Solution
Correct Answer
(A) Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\).
Step-by-step Solution
Detailed explanation
If the number is less than one, the zero on the right of decimal point but to the left of the first non-zero digit are not significant, i.e. in \(\underline{\mathbf{0}} \underline{\underline{00} 764 \text {, }}\) the underlined zeroes are not significant. The number of…
