Question

Ratio of the SI units to the CGS units of retardation is

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

Answer 1

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

Retardation is negative acceleration
$SI$ units $=\frac{m}{s^2}$
CGS units $=\frac{cm}{s^2}$
Ratio of SI to CGS units is
$100:1$
