Units & Dimensions

If E and G respectively denote energy and gravitational constant, then EG\frac{E}{G} has the dimensions of:

Show answer and solution

Answer: (b)

  1. [E]=[ML2T−2][E] = [\mathrm{ML^2T^{-2}}], [G]=[M−1L3T−2][G] = [\mathrm{M^{-1}L^3T^{-2}}]
  2. [E][G]=[M2L−1T0]\frac{[E]}{[G]} = [\mathrm{M^{2}L^{-1}T^{0}}]
  3. So the answer is (b).
