Question

dimensional formula of gravitational constant..​

Answer 1

$\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}⋆$

we know, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2].

• Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.

Answer 2

G=6.67×10^-11 Nm²/Kg²….

We know unit of Force is Newton n it's dimensional formula is MLT^-2 …

Now the unit of G is …Nm²/Kg²…

m² is meter square = L²

Kg² is M²

Therefore

Nm²/Kg² = MLT^-2 × L² × M^-2 ..

That is [M^-1 L^3 T^-2]
