The velocity of water waves $v$ may depend upon 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

  • A

    ${v^2} \propto \lambda {g^{ - 1}}{\rho ^{ - 1}}$

  • B

    ${v^2} \propto g\lambda \rho $

  • C

    ${v^2} \propto g\lambda $

  • D

    ${v^2} \propto {g^{ - 1}}{\lambda ^{ - 3}}$

In a particular system of units, a physical quantity can be expressed in terms of the electric charge $c$, electron mass $m_c$, Planck's constant $h$, and Coulomb's constant $k=\frac{1}{4 \pi \epsilon_0}$, where $\epsilon_0$ is the permittivity of vacuum. In terms of these physical constants, the dimension of the magnetic field is $[B]=[c]^\alpha\left[m_c\right]^\beta[h]^\gamma[k]^\delta$. The value of $\alpha+\beta+\gamma+\delta$ is. . . . .
