Question 103 of 149

If $E,L,M$ and $G$ denote the quantities as energy, angular momentum, mass and constant of gravitation respectively, then the dimensions of $P$ in the formula $P=E{L}^{2}{M}^{-5}{G}^{-2}$ are:

Show answer and solution

Answer: (D) $\left[{M}^{0}{L}^{0}{T}^{0}\right]$

P=E{L}^{2}{M}^{-5}{G}^{-2}

P=\left[M{L}^{2}{T}^{-2}\right]{\left[M{L}^{2}{T}^{-1}\right]}^{2}\left[{M}^{-5}\right]{\left[{M}^{-1}{L}^{3}{T}^{-2}\right]}^{-2}

P=\left[{M}^{0}{L}^{0}{T}^{0}\right]
