Question

The ratio of SI unit of G to its CGS unit is _______.

• A. $100:1$
• B. $1000:1$
• C. $10:1$
• D. $10000:1$

Answer 1

The correct option is B $1000:1$

We know that SI unit of G $=m^3/s^{2}kg=\left(100cm{)}^3/s^2\right(1000g)={10}^{6}c{m}^3/{10}^{3}g{s}^2={10}^{3}c{m}^3/g{s}^2$

Also the CGS unit of G $=c{m}^3/g{s}^2$

$\Rightarrow \frac{SI}{CGS}=1000$

Hence correct answer is option $B$
