ASSERTION

nm is not same as mN

REASON

$1nm = 10^{-9}$m and $1mN=10^{-3}$N

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

SOLUTION
Nanometer (nm) is the unit of length and milinewton (mN) is the unit of force. So they can not same.
Also, $1 nm=10^{-9}m$ and $1 mN=10^{-3}N$
Thus, assertion and reason are correct and reason is the correct explanation for assertion.
