Question

The SI unit of the universal gravitational constant G is (A) Nm kg -2 (B) Nm 2 kg -2 (C) Nm 2 kg -1 (D) Nmkg -1

Tardigrade Admin · Accepted Answer

SI unit of universal gravitational constant G is
We know

F = \frac{G M _{1} M _{2}}{R ^{2}}

Here

M_{1}

and

M_{2}

are mass

R =

Distance between them

F =

Force

G = \frac{F R ^{2}}{M _{1} M _{2}} = \frac{N - m ^{2}}{k g ^{2}}

So, Unit of

G = N - m^{2} k g^{- 2}
