Question

pls answer this question guys....​

Answer 1

Consider the given equation,

μ = A + B/λ + C/λ² ______ ( i )

Dimensional formula of λ = [ L ] Dimensional formula of μ = [ MLT^-1 ]

Since, dimension of same quantity adds.

Put dimensions in ( i )

On putting dimensions we get

Dimension of A = L

Dimension of B = No Dimension

Dimension of C = L²

Hence, option 4) is correct.

Hope it helps. ^_^
