Solution

The correct option is C B
For bubble tube 'A' ,

$α_{A} = 20^{''} p e r 2 m m$
$R_{A} = \frac{2 \times 10^{- 3} \times 206265}{20} = 20.6265 m$

For bubble tube 'B' ,

$α_{B} = 10^{''} p e r 2 m m$

$R_{B} = \frac{2 \times 10^{- 3} \times 206265}{10}$

$= 41.253 m$

Large the value of R, more is the sensitivity of bubble. Hence, bubble tube 'B' is more is sensitive.
