If the speed of light \{c\} , acceleration due to gravity \{g\} and pressure \langle \rho \rangle are taken as the fundamental quantities, then the dimension of gravitational constant is
Text Solution
Verified by ExpertsThe correct answer is:
B
Let [G] \propto c^{x} g^{y} \rho^{2}
by substituting the following dimensions :
[G] = [M^{-1} L^{3} T^{-2}], [c] = [L T^{-1}], [g] = [L T^{-2}]
[\rho] = [M L^{-1} T^{-2}]
and by comparing the powers of both sides
we can get x=0, y=2, z=-1
[G] r \ddot{c} g^{2} p^{1}
