Question

explain formula and relationship between g and G and find the value of g​

Answer 1

Answer:

The value of G = 6.67* 10^-11 Nm^2/ kg^2

The value of g = 9.8 m/ s^2

Hope this helps you ..........

Answer 2

Answer:

The earth's mass = M

The object's mass on earth = m

According to the equation,

F=\frac{G M m}{r^{2}}F=

r

2

GMm

Where,

r defines the distance between earth and the object and G is universal gravitational constant.

Here, F is the force applied by the Earth on the object and the object accelerates towards earth with an acceleration g (acceleration due to gravity)

Therefore, F = mgF=mg

On substituting F in above equation, we get,

m g=F=\frac{G M m}{r^{2}}mg=F=

r

GMm

\Rightarrow g=\frac{G M}{r^{2}}⇒g=
