Question

write the SI unit and value of universal gravitational constant​

Answer 1

The dimensions assigned to thegravitational constant are force times length squared divided by mass squared; this is equivalent to length cubed, divided by mass and by time squared: In SI base units, this amounts to meters cubed per kilogram per second squared: In cgs, G can be written as G ≈6.674×10−8cm3⋅g−1⋅s−2.

Answer 2

S.I unit=meters cubed per kilogram per second squared

Value of G =6.674×10−8 m3⋅kg−1⋅s−2.
