Question

Explanaton of. Si unit universal gravitational in to its cgs unit

Answer 1

Universal gravitational constant  = G 

Newton's gravitational force = F = G M m /d²
=>    G = Force distance² /mass²
            = mass * distance /time²  * distance²/ mass²
        G = distance³ /(time² mass)

SI units:  m³ /sec² kg) 
          =  (100 cm)³ / (sec² - 1000 gm)
          =  1000 cm³/ gm-cm²

CGS units of G are   cm³/cm-sec²

Ratio = 1000.

Answer 2

The Indian Atomic Energy Commission (AEC) is the main policy body. The Nuclear Power Corporation of India Ltd (NPCIL) is responsible for design, construction, commissioning and operation of thermal nuclear power plants.
