Assertion : When we change the unit of meansurement of a quantities its numerical value change.
Reason : smaller the unit of meansurement smaller is its numerical value.
A. If both the asseration and reason are true and reason is a true explanation of the asseration.
B. If both the asseration and reason are true but the reason is not the correct explanation of asseration.
C. If the asseration is ture but reason is false.
D. If both the asseration and reason are false.

Answer 1

Correct Answer - c
We know that `Q = n_(1) u_(1) = n_(2)u_(2)` are the two unit of meansurements of the quantity `Q` and `n_(1), n_(2)` are their respectively numerical value from relation `Q_(1) = n_(1) u_(1) = n_(2)u_(2) ,nu = "constant" rArr n prop 1//u` i.e., smaller the unit of meansurement , greater is the numerical value.
