Answer:
N (kg)^-2 m²
Explanation:
The Newton's Law of Gravitation gives,
F = (G × M1 × M2)/d²
where,
F = Gravitational force,
G = Universal constant of gravitation,
M1 = Mass of the first object,
M2 = Mass of the second object,
d = Distance between the objects.
Hence, G = (F × d²)/(M1 × M2)
Unit of F = Newton (N),
Unit of d = metre (m),
Unit of M1, M2 = kilogram (kg).
Therefore,
unit of G = (N × m²)/(kg × kg)
= N m² / kg²
= N (kg)^-2 m²
