Question
A capacitor of plate area A has charge Q, then electrostatic energy density stored between the plates will beChoose answer:
Solution
The electrostatic energy density (u) stored in a capacitor can be calculated using the formula:
u = Q² / (2 * ε * A * d)
where: Q is the charge on the capacitor, ε is the permittivity of the medium between the plates, A is the area of one of the plates, and d is the distance between the plates.
However, the question does not provide the values for ε and d, so we cannot calculate the exact energy density. But we can say that the energy density is directly proportional to the square of the charge and inversely proportional to the area of the plates.
