Question

Convert 7 pm into $\mu m$

• A. $7\times {10}^{-6}\mu m$
• B. $14\times {10}^{-6}\mu m$
• C. $7\times {10}^{-3}\mu m$
• D. $14\times {10}^{-3}\mu m$

Answer 1

The correct option is A $7\times {10}^{-6}\mu m$

Let 7 pm = $\left(x\right)$ $\mu$m

Now lets convert both LHS & RHS into meter
$7\times \left({10}^{-12}\right)m=\left(x\right)\times {10}^{-6}m$
On solving we get $x=7\times {10}^{-6}$
So $7pm=(7\times {10}^{-6})\mu m$

Hence the correct option is A.
