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

A

`n_1u_1=n_2u_2`

B

`n_1u_1+n_2u_2=0`

C

`n_1n_2=u_1u_2`

D

`(n_1+u_1)l=(n_2+u_2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Pysical quantity `(p)=` numerical value `(n)xxunit(u)` If pysical quantity remains constant then `nprop(1)/(u)` `because` `n_1u_1=n_2u_2`.
