The accuracy in the measurement of the diameter of hydrogen atom measured as $$1.06 \times { 10 }^{ -10 }$$ m is :


ANSWER

$$\dfrac { 1 }{ 106 } $$


SOLUTION
Calculating accuracy is similar to calculating the minimum possible error in a measurement.
Now diameter $$ = 1.06 \times 10^{-10} m $$
Minimum deviation possible $$ = 0.01 \times 10^{-10} m$$
Accuracy $$= \dfrac{0.01}{1.06} = \dfrac{1}{106}$$
