Question
The energy density in the electric field created by a point charge falls off with distance from the point charge as(A) $\frac{1}{r}$(B) $\frac{1}{r^{2}}$(C) $\frac{1}{r^{3}}$(D) $\frac{1}{r^{4}}$
Step 1
Step 1: The energy density (U) in an electric field is given by the equation: \[U = \frac{1}{2} \epsilon_0 E^2\] where \(\epsilon_0\) is the permittivity of free space and E is the electric field. Show more…

A sphere of radius $R$ has a uniform distribution of electric charge in its volume. At a distance $\mathrm{x}$ from its centre, (for $\mathrm{x}<\mathrm{R})$, the electric field is directly proportional to ...... (A) $\mathrm{x}$ (B) $\mathrm{x}^{-1}$ (C) $x^{-2}$ (D) $\mathrm{x}^{2}$
Let $\mathrm{P}(\mathrm{r})\left[\mathrm{Q} /\left(\pi \mathrm{R}^{4}\right)\right] \mathrm{r}$ be the charge density distribution for a solid sphere of radius $\mathrm{R}$ and total charge $\mathrm{Q}$. For a point ' $\mathrm{P}$ ' inside the sphere at distance $\mathrm{r}_{1}$ from the centre of the sphere the magnitude of electric field is (A) $\left[\mathrm{Q} /\left(4 \pi \epsilon_{0} \mathrm{r}_{1}^{2}\right)\right]$ (B) $\left[\left(\mathrm{Qr}_{1}^{2}\right) /\left(4 \pi \in{ }_{0} \mathrm{R}^{4}\right)\right]$ (C) $\left[\left(\mathrm{Qr}_{1}^{2}\right) /\left(3 \pi \epsilon_{0} \mathrm{R}^{4}\right)\right]$
In the above problem, the energy density associated with the electric field will be (A) $\frac{1}{2} C V^{2}$ (B) $\frac{1}{2} \frac{q^{2}}{C}$ (C) $\frac{1}{2} \frac{\varepsilon^{2}}{E}$ (D) $\frac{1}{2} \varepsilon_{0} E^{2}$
