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 ofA. TimeB. AngleC. MassD. Length |

Answer» Correct Answer - B ` (E J ^(2))/(M^(5) G^(2)) = ([ML^(2)T^(-2)][ML^(2)T^(-1)]^(2))/(M^(5)xx[M^(-1)L^(3)T^(-2)]^(2)) = M^(0) L^(0) T^(0)` This comes out to be dimensionless and angle is also dimensionless. |
