Assertion: When we change the unit of measurerment of a quantity its numerical value changes.
Reason: Smaller the unit of measurement smaller is its numerical value.

Options

A. If both assertion and reason are true and reason is the correct explation of assertion.
B. If both assertion but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Answer

c

Explanation

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 = n_(1) u_(1) = n_(2)u_(2) ,n u = "constant" rArr n prop 1//u` i.e., smaller the unit of meansurements greater is the numerical value.
