If $E, m, J$ and $G$ represent energy, mass, angular momentum and gravitational constant respectively, then the dimensional formula of $\frac{E J^{2}}{m^{5} G^{2}}$ is

Options:

Answer:

Solution:

$[E] = [M L^{2} T^{- 2}]$

${[J]}^{} = [M L^{2} T^{- 1}]$

$[G] = [M^{- 1} L^{3} T^{- 2}]$

$\frac{[E] {[J]}^{2}}{{[M]}^{5} {[G]}^{2}} \frac{[M L^{2} T^{- 2}] {[M L^{2} T^{- 1}]}^{2}}{[M^{5}] {[M^{- 1} L^{3} T^{- 2}]}^{2}} = [M^{0} L^{0} T^{0}]$
