If `E , M , J , and G` , respectively , denote energy , mass , angular momentum , and gravitational constant , then `EJ^(2) //M^(5) G^(2)` has the dimensions of

Explanation

D.F of `(EJ^(2))/(M^(5) G^(2))`
Substituing `D.F` of `E,J,M` and `G` in above formula
`= (ML^(2)T^(-2)[ML^(2)T^(-1)]^(2))/(M^(5)[M^(-1)L^(3)T^(-2)]^(2)) = [M^(0) L^(0) T^(0)]`
