Question

Which one of the following represents the correct dimensions of the quantity : `x=(eta)/(rho)`, where `eta`=coefficient of visocosity and `rho` =the density of a liquid?
A. `[ML^(-2)T^(-1)]`
B. `[ML^(-4)T^(-2)]`
C. `[ML^(-5)T^(-2)]`
D. `[M^(0)L^(2)T^(-1)]`

Answer 1

Correct Answer - D
`[(eta)/(rho)]=[(ML^(-1)T_(-1))/(ML^(-3))]=[M_(0)L^(2)T_(-1)]`.
