Suppose we employ a system in which in which the unit of mass equals `100 kg` , the unit of length equals `1 km` and the unit of time `100 s` and call the unit of energy eluoj ( joule written in reverse order), then what is the relation between eluoj and joule?

Explanation

`[E] = [ML^(2)T^(-2)]`
` = [ 100 kg] xx [ 1 km]^(2) xx [ 100 s]^(-2)`
` = 100 kg xx 10^(6) m^(2) xx 10^(-4) s^(-2)`
`= 10^(4) xx m^(2) s^(-2) = 10^(4) J`
