The value fo universal gravitationla constant `G` in `CGS` system is `6.67xx10^(-8)` dyne `cm^(2) g^(-2)`. Its value in `SI` system is

Options

A. `6.67 xx 10^(11) Nm^2 Kg^(-2)`
B. `6.67 xx 10^(-5) Nm^(2) Kg^(-2)`
C. `6.67 xx 10^(-10) Nm^2 kg^(-2)`
D. `6.67 xx 10^(-9) Nm^(2) Kg^(-2)`

Answer

A

Explanation

`6.67 xx 10^(-8) "dyne" cm^2 (gm)^(-2)`
` = 6.67 xx 10^(_8) (10^(-5) N) (10^(-2) m)^2 (10^(-3) kg)^(-2)`
