fill in the blanks by suitable conversion of units : (i) 5ms^(-2) = ……. Km h^(-2) (ii) G = 6.67 xx 10^(-11) Nm^2 kg^(-2) =….. Cm^3 s^(-2) g^(-1)

Answer»

SOLUTION :`G=6.67xx10^(-11)Nm^(2)kg^(-2)`
`=6.67xx10^(-11)(KGMS^(-2))(m^(2)kg^(-2))`
`=6.67xx10^(-11)kg^(-1)m^(3)s^(-2)`
`=6.67xx10^(-11)(1000g)^(-1)(100CM)^(3)(s^(-2))`
`=6.67xx10^(-11)xx(1)/(1000)xx100xx100xx100g^(-1)cm^(3)s^(-2)`
`=6.67xx10^(-8)g^(-1)cm^(3)s^(-2)`.
