Question

The value of G in CGS system is 6.67×10^-8 dyne cm^2 g^-2. Calculate the value in SI unit.​

Answer 1

Answer:

6.67 × 10^-8 dyne.cm²/g²

we know ,

1 dyne = 10^-5 N

1 cm = 10^-2 m

1 g = 10^-3 kg

use this here ,

6.67 × 10^-8 × ( 10^-5) .(10^-2)²/(10^-3)²

= 6.67 × 10^-8 { 10^-5× 10^-4 /10^-6} Nm²/kg²

= 6.67 × 10^-8- × 10^-3 N.m²/kg²

= 6.67× 10^-11 Nm²/kg²
