Question

The ratio of SI units to CGS units of retardation is :

• A. 10^-2
• B. 10²
• C. 10
• D. 10^-1

Answer 1

The correct option is B

10²

As we know that;

1. Retardation is a negative value of acceleration.
2. The SI unit of retardation is m/s².
3. CGS (Centi-gram-second) unit of retardation is cm/s².
4. $1m={10}^{2}cm$

So the ratio will be given by;

$=\frac{m/s^2}{cm/s^2}=\frac{{10}^{2}cm/s^2}{cm/s^2}={10}^2.$

Therefore, the ratio of SI to CGS units is 100.

Hence, the correct option is (B).
