Question

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
A. length
B. angle
C. mass
D. time

Answer 1

Correct Answer - B
`(ML^(2)T^(-2)(MLT^(-1)L)^(2))/(M^(5)(M^(-1)L^(3)T^(-2)))=M^(0)L^(0)T^(0)`
