given that v is the speed r is radius and g is acceleration due to gravity which of the following is dimensionless
A) v^2r/g
B) v^2/ rg
C) v^2g/ r
D) v^2rg
Plz give ans with explanation
Dear Student ,
v2 / rg is the term which is dimensionless .
Because v2 has the dimension of [ L2T-2] and rg has also dimension of [L2T-2] .
So the ratio of v2/rg is a dimensionless quantity .
