If `u_(1) and u_(2)` are the selected in two system of measurement and `n_(1) and n_(2)` their nomerical values, then

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))`

Text Solution

Verified by Experts

The correct Answer is:
a
Physical quantity `(p) = "Numerical value" (n) xx "Unit" (u)`. if physical quantity remain constant then
`n = 1//u :. N_(1)u_(1) = n_(2)u_(2)`
