Question

Let Q denote the charge on the plate of a capacitor of capacitance C. The dimensional formula for `"Q"^2/"C"` is ______.

Options

• [L²M²T]

• [LMT²]

• [L²MT^-2]

• [L²M²T²]

Answer 1

Let Q denote the charge on the plate of a capacitor of capacitance C. The dimensional formula for `"Q"^2/"C"` is [L²MT^-2].

Explanation:

We know that `"Q"^2/"C"` is energy of capacitor, so it represent the dimension of energy = [ML²T^-2].
