Physics

Let $$Q$$ denote the charge on the plate of a capacitor of capacitance $$C$$. The dimensional formula for $$\dfrac {Q^2}{C}$$ is


ANSWER

$$[L^2MT^{-2}]$$


SOLUTION
The term $$\dfrac {Q^2}{2C}$$ is the formula of energy stored in a capacitor so it has the dimension of energy $$=[ML^2T^{-2}]$$
