In the relation: $\mathrm{P}$ is pressure, $\mathrm{Z}$ is distance, $\mathrm{k}$ is Boltzmann constant and $\theta$ is the temperature. The dimensional formula of $\beta$ will be

• Correct answer
  A

  $\left[\mathrm{M}^{0} \mathrm{~L}^{2} \mathrm{~T}^{0}\right]$
• B

  $\left[\mathrm{M}^{1} \mathrm{~L}^{2} \mathrm{~T}^{1}\right]$
• C

  $\left[\mathrm{M}^{1} \mathrm{~L}^{0} \mathrm{~T}^{-1}\right]$
• D

  $\left[\mathrm{M}^{0} \mathrm{~L}^{2} \mathrm{~T}^{-1}\right]$

Hence, the correct answer is option: 'A'.
