Embibe Experts Solutions for Exercise 2: Assignment

The energy stored in a parallel plate capacitor of capacitance $C$, having potential difference between the plates $V$ and charge $Q$ is given by

The energy density in parallel plate capacitor is (where $E$ is the electric field between the plates)

Four point charges $+q,+q,-q,-q$ are placed at the corners of a square as shown in figure. At the centre of the square

In the electric field of a point charge $Q$ which is kept at point $O$, a certain charge is carried from $A$ to $B$ and from $A$ to $C$. If work done from $A$ to $B$ is $W_1$ and from $A$ to $C$ is $W_2$, then (Where $OA=OB=OC$)

If $V_1$ and $V_2$ are potentials of points $A$ and $B$ respectively then ratio of the charge on capacitor $C_1$ and $C_2$ is $\left(V_1\ne V_2\right)$

The charge on $2\mu \mathrm{F}$ capacitor as shown in circuit is

At the surface of a charged conductor, electrostatic field must be_____ to the surface at every point.

Five capacitors are connected as shown in the diagram. Calculate equivalent capacitance between the points $x$ and $y$.
