The accuracy in the measurement of speed of light measured as $$3.00\times { 10 }^{ 8 }\ m/s$$ is :


ANSWER

$$\dfrac { 1 }{ 3 }\%$$


SOLUTION
Accuracy is defined as the possible error in the calculation. 
Now, speed of light here is measured as $$ 3.00\times { 10 }^{ 8 }$$ which is measured up to $$ 0.01\times { 10 }^{ 8 }$$
Thus accuracy, in percentage $$= \dfrac { 0.01\times { 10 }^{ 8 } }{ 3.00\times { 10 }^{ 8 } } \times 100 = \dfrac { 1 }{ 3 } $$%
