If E and G respectively denote energy and gravitational constant, then E G has the dimensions of:

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