Question

If the value of universal gravitational constant is `6.67xx10^(11) Nm^2 kg^(-2),` then find its value in CGS system.

Answer 1

`G=6.67xx10^(-11)nm^(2)kg^(-2)`
`=6.67xx10^(-11)(kg ms^(-2))m^(2)kg^(-2)`
`=6.67xx10^(-11)(m^(3))(s^(-2))(kg^(-1))`
`=6.67xx10^(-11)(10^(2)cm)^(3)(s^(-2))(10^(3)kg^(-1))`
=`6.67xx10^(-8)cm^(3)g^(-1)s^(-2)`
=`6.67xx10^(-8)"dyne"^(-cm^(2))g^(-2)`
