Verified by Experts
The correct answer is:
D

Given, m = mass = [ M ], v = velocity = , ρ ρ = density = , g = acceleration due to gravity = [ LT –2 ]

By substituting, the dimension of each quantity we can check the accuracy of the formula

= [ M ]

L.H.S. = R.H.S. i.e., the above formula is Correct .
