Solution

The correct option is A
2.0 cm

The thickness fo the cube = $t = 6.0 c m$ . The shift in the position of the printed letters is
$△ t = (1 - \frac{1}{μ}) t$
$= (1 - \frac{1}{1.5}) \times 6.0 c m = 2.0 c m .$

The correct option is A 2.0 cm The thickness fo the cube = t = 6.0 cm. The shift in the position of the printed letters is △t=(1−1μ)t =(1−11.5)×6.0cm=2.0cm.
