Question

What is the value of universal constant g and it's unit

Answer 1

Hey!

_____________________________

If you are talking about small 'g', then here we go-

'g' is acceleration due to gravity, it is the acceleration produced in a body in free fall due to the gravitational force of earth on the body.

Value of acceleration due to gravity-

Value of 'g' can be calculated from relation between 'g' and 'G'

We know,

g= GM/R^2

G= 6.67×10^-11
M (of earth)= 6×10^24 kg
Radius (of earth)= 6.4×10^6 m

g= 6.67×10-11×6×10^24/(6.4×10^6)^2
g= 9.8m/s^2

Sometimes, to make the calculations easy, we take 'g' as 10 m/s^2.

Answer 2

Answer:

The value of G universal gravitational constant is 6.67×10^ −11 Nm 2 /kg^ 2

It’s S.I. the unit is Nm ^2 /Kg^ 2
