The velocity of water wave `v` may depend on their wavelength `lambda`, the density of water `rho` and the acceleration due to gravity `g`. The method of dimensions gives the relation between these quantities as

Options

A. `V^(2) prop g^(-1) gamma^(-1)`
B. `V^(2) prop g lambda`
C. `V^(2) prop g lambda rho`
D. `V^(2) prop g^(-1) lambda^(-3)`

Answer

b

Explanation

See question 38 above.
`v prop sqrt(g lambda)rArr v^(2) prop g lambda`
