Question

If ‘u’ is the unit and ‘n’ is the numerical value then (a) n is directly proportional to u (b) n is inversely proportional to u ​(c) n is inversely proportional to u^2 (d) n is directly proportional to u^2

Answer 1

n is inversely proportional to u
i.e if unit is
incresing . numeic value decreases

lets we take example of velocity
100m/s= 27.78km/h

Answer 2

They are b) n is inversely proportional to u ...
for example
1 m = 100 cm
here meter unit is bigger hence small magnitude but 100 is large number but unit is smaller ....
