Question

Which one exception, each of the following units can be used to express mass. What is the exception?

• A. $Newton$
• B. $Gram$
• C. $kilogram$
• D. $N{s}^2/m$

Answer 1

The correct option is A $Newton$

We know that

$f=ma$

Now, for f, the S.I unit is Newton, for acceleration is $m/s^2$

S.I unit of $\left(F/a\right)$ will be $\left(N/m{s}^2\right)$

But, $\frac{F}{\alpha }=mass$

So, $N{s}^2/m=kg$

Since, $kg$ is the S.I unit of mass

$\therefore$ Newton is the correct answer.
