Dimensions of universal gravitational constant \( (G) \) in terms of Planck’s constant \( (h) \), distance \( (L) \), mass \( (M) \) and time \( (T) \) are ________.
\( \left[hTL\,M^{-2}\right] \)
\( \left[hT^{-1}L\,M^{-2}\right] \)
\( \left[hTL^{2}M^{-2}\right] \)
\( \left[h^{-1}T^{-1}L\,M^{-2}\right] \)
