Question

dimensions of universal constant of gravitation is......​

Answer 1

Dimensions of universal constant of gravitation is M-1 L3 T-2

Mark me as brainliest

Answer 2

G = Fd²/Mm

We know,

Dimensions of F = M¹L¹T-²

∴ Dimensions of G = (M¹L¹T-²)(L)²/(M)(M)

⇒ Dimensions = M-¹L³T-² {Answer}

More:-

• Examples dimensionless quantity = Refractive index, relative density. {M⁰L⁰T⁰.}
• Dimensions of,

1. Length = L
2. Time = T
3. Area = L × L = L²
4. Mass = M
5. Temperature = K
6. Angle = θ
7. Current = A.
