If \(C\), the velocity of light, \(g\) the acceleration due to gravity and \(P\) the atmosphenic pressure be the fundamental quantities in M.K.S. system, then the dimensions of length will be same as that of
  1. \(C / g\)
  2. \(C / P\)
  3. \(P C g\)
  4. \(C^{2} / g\)

Solution

\(\frac{C^{2}}{g}=\frac{L^{2} T^{-2}}{L T^{-2}}=[L]\)
