If N A , N B and N C are the number of significant figures in A = 0 . 001204 m , B = 43120000 m , and C = 1 . 200 m respectively then
Options
- AN A = N B = N C
- BN A > N B > N C
- CN A < N B < N C
- DN A > N B < N C
Correct answer
A. N A = N B = N C
Step-by-step solution
Significant figures are calculated through certain rules: (i) All the digits that have no zero are significant. (ii) Zeros that are written at the right hand side of the last non-zero digit in a number with the decimal are significant, while if the decimal is not present then the zeros are not significant. (iii) The zeros that are written before non-zero digits are not significant. (iv) Zeros that are written between the non- zero digits are significant. So, here number of significant figures in A , B and C are fou
