CONCEPT:

Universal gravitational constant:

  • The gravitational force between two bodies of unit masses separated by a unit distance is known as the universal gravitational constant.
  • The value of the universal gravitational constant is the same at every point in the universe.
  • The value of the universal gravitational constant in the SI system is given as,

⇒ G = 6.67 × 10-11 N-m2/kg2

  • The value of the universal gravitational constant in the CGS system of unit is given as,

⇒ G = 6.67 × 10-8 dyne-cm2/gm2​

EXPLANATION:

We know that the value of the universal gravitational constant in the CGS system of unit is given as,

⇒ G = 6.67 × 10-8 dyne-cm2/gm2

  • Hence, option 2 is correct.
