  • Four charges $q,2q,-q,-2q$ are placed at the corners of a square of side $a$. Find the electric field at a point distance $z$ above the center of the square. \input{\QBankDir/em-que-01016}
  • The electric field due to a line segment of length $2L$, and carrying a uniform line charge $\lambda$ at a distance $d$ above the mid point is given by $$ E = \frac{1}{4\pi\epsilon_0} \, \frac{2\lambda L}{d \sqrt{d^2 +L^2}}$$ Using the above result find the electric field at a distance $z$ above the center of a square loop ( side $2L$) carrying a uniform line charge $\lambda$.

A macroscopic system can be in any one of the two energy levels labeled $1$ and $2$, with probabilities $p_1$ and $p_2$ respectively. The degeneracy of the energy level labeled $1$ is $g_1$ and that of the energy level labeled 2 is $g_2$. Show that entropy of the system is given by,

\begin{eqnarray}
S &=& -k_B \sum_{i=1}^2 p_i\ln\ p_i+\sum_{i=1}^2 p_i\left[ k_B\ln\ g_i\right]
\end{eqnarray}
