The value of the universal gravitational constant in CGS system of units is equal to:

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.
