Question

dimension of gravitational constant with proper derivation ? ​

Answer 1

Answer:

The dimensions assigned to the gravitational constant are force times length squared divided by mass squared; this is equivalent to length cubed, divided by mass and by time squared: In SI base units, this amounts to meters cubed per kilogram per second squared: In cgs, G can be written as G ≈ 6.674×10−8 cm3⋅g−1⋅s−2.

Answer 2

Answer:

solved

Explanation:

Newtons gravitational law states that the force between two bodies of masses M and m and distance between their centres R is F = GmM/R²

for a body on the surface of earth this force = the weight w

w = mg = GmM/R²

g = GM/R²

G = gR²/M

dimensions of G is L/T²(T²)/M = L/M
