Motion In Straight Line

Question

Wired Faculty App

Does the value of gravitational constant depend on the system of unit used?

Solution

Yes, the values of gravitational constant in SI and CGS are different.
In S.I. unit -

straight G space equals space 6.67408 space cross times space 10 to the power of negative 11 end exponent space straight m cubed space kg to the power of negative 1 end exponent space straight s to the power of negative 2 end exponent

In cgs unit,

straight G space equals space 6.674 space cross times space 10 to the power of negative 8 end exponent space cm cubed space straight g to the power of negative 1 end exponent space straight s to the power of negative 2 end exponent
