The value of universal gravitational co...

The value of universal gravitational constant is `6.67xx10^(-8) "dyne" g^(-2) cm^2.` What is its value in Mks system?

Text Solution

Verified by Experts

The correct Answer is:
`6.67 xx 10^(11) Nm^2 kg^(-2)`

`G = 6.67xx10^(-8) ("dyne" cm^2)/((gram)^2)`
`=6.67 xx10^(-8) ((10^(-5)N)(10^(-2)m)^2)/((10^(-3)kg)^2`
`G = 6.67xx10^(-11)Nm^2kg^(-2)`
