Question

The ratio of SI units to CGS units of retardation is

• A. ${10}^{-2}$
• B. ${10}^2$
• C. $10$
• D. ${10}^{-1}$

Answer 1

The correct option is B ${10}^2$

SI unit of retardation is $m{s}^{-2}$ and CGS unit is $cm{s}^{-2}$.

Also, we know that $1m=100cm$

Thus ratio,

$ratio=\frac{m{s}^{-2}}{cm{s}^{-2}}$

$\Rightarrow ratio=\frac{100cm{s}^{-2}}{cm{s}^{-2}}$

$\Rightarrow ratio={10}^2$
