JEE MAIN - Physics (2024 - 8th April Morning Shift - No. 5)
In an expression $$a \times 10^b$$ :
$$a$$ is order of magnitude for $$b \leq 5$$
$$b$$ is order of magnitude for $$a \leq 5$$
$$b$$ is order of magnitude for $$a \geq 5$$
$$b$$ is order of magnitude for $$5< a \leq 10$$
Explicació
In expression $$a \times 10^b$$, If $$a \leq 5 ; a \approx 1$$ by round off
$$\Rightarrow$$ Order $$B$$
