Question

The thickness of paper is $0.004$ m and that of another paper is $0.008$ m. Compare their sizes.

• A. Paper-1 is double thicker than paper-2.
• B. Thickness of paper-1 is half the thickness of paper-2.
• C. Thickness of paper-1 is one-fourth of the thickness of paper-2.
• D. Paper-1 and paper-2 are both equally thick.

Answer 1

Answer: (B)

Thickness of paper-1 is half the thickness of paper-2.

$0\cdot 004=4\times {10}^{-3}$ m

$0\cdot 008=8\times {10}^{-3}$

Now
$\frac{0\cdot 004}{0\cdot 008}=\frac{4\times {10}^{-3}}{8\times {10}^{-3}}=\frac{4}{8}=\frac{1}{2}$

$\therefore$ Thickness of paper-1 is half than paper-2
