If \[{{u}_{1}}\] and \[{{u}_{2}}\] are the units selected in two systems of measurement and \[{{n}_{1}}\] and \[{{n}_{2}}\] their numerical values, then [SCRA 1986]

\[{{n}_{1}}{{u}_{1}}+{{n}_{2}}{{u}_{2}}=0\]

\[{{n}_{1}}{{u}_{1}}={{n}_{2}}{{u}_{2}}\]

\[{{n}_{1}}{{n}_{2}}={{u}_{1}}{{u}_{2}}\]

\[({{n}_{1}}+{{u}_{1}})=({{n}_{2}}+{{u}_{2}})\]

If \[{{u}_{1}}\] and \[{{u}_{2}}\] are the units selected in two syste

1.	If \[{{u}_{1}}\] and \[{{u}_{2}}\] are the units selected in two systems of measurement and \[{{n}_{1}}\] and \[{{n}_{2}}\] their numerical values, then [SCRA 1986]
A.	\[{{n}_{1}}{{u}_{1}}={{n}_{2}}{{u}_{2}}\]
B.	\[{{n}_{1}}{{u}_{1}}+{{n}_{2}}{{u}_{2}}=0\]
C.	\[{{n}_{1}}{{n}_{2}}={{u}_{1}}{{u}_{2}}\]
D.	\[({{n}_{1}}+{{u}_{1}})=({{n}_{2}}+{{u}_{2}})\]
Answer» B. \[{{n}_{1}}{{u}_{1}}+{{n}_{2}}{{u}_{2}}=0\]
