Imagine a system of unit in which the unit of mass is 10 kg , length is 1 km and time is 1 min. Then, 1 J in this system is equal to

In the formula $$X=3 Y Z^2, X$$ and $$Z$$ have dimensions of capacitance and magnetic induction respectively. The dimensions of $$Y$$ is MKS system are.

A quantity $X$ is given by $$\frac{\varepsilon_0 A}{L} \frac{\Delta V}{\Delta t}$$, where $$\varepsilon_0$$ is the permittivity of free space, $$L$$ is the length, $$A$$ is area, $$\Delta V$$ is the potential difference and $$\Delta t$$ is time interval. The dimensional formula for $$X$$ is the same as that of
