Given data

*The given mass of the fixture is m = 1.4 kg

*The given force is F = 21 N

The formula for the normal force is given as


N=mg

Substitute the known values in the above expression as


\begin{gathered} N=(1.4)(9.8) \\ =13.72\text{ N} \end{gathered}

Hence, the normal force is N = 13.72 N
