due to gravity.

Universal G Nm²/kg²

Gravitational

Constant

Answer 2

Answer:

acceleration due to gravity symbolised by 'g'.

It's si unit is meter per second square (m/s2)

Gravitational constant symbolised by 'G'.

It's SI unit is Newton meter square per kilogram square (N m2 /Kg2 )

Explanation:

for 'g'

F= ma

F =mg

g=F/m

=Kg.ms2 / Kg

=m/s2

for 'G'

G= F × r2 / M1 × M2

= N × m2 / Kg × Kg

= N× m2/ Kg2

= N M2 / kg2
