b In a uniform electric field, equal displacements cause equal changes in potential. Each of displacements $OA,$ $AB$ and $BP$ cause a drop in potential of $2 \mathrm{V}$.
Thus, the potential at $P=10-2-2-2=4 V$

Two identical electric point dipoles have dipole moments $\overrightarrow{p}_{1}= p\hat i$ and $\overrightarrow{p}_{2}=- p\hat i$ and are held on the $x-$axis at distance $'a'$ from each other. When released, they move along the $x-$axis with the direction of their dipole moments remaining unchanged. If the mass of each dipole is $'m',$ their speed when they arc infinitely far apart is
A capacitor of capacitance $900\,\mu F$ is charged by a $100\,V$ battery. The capacitor is disconnected from the battery and connected to another uncharged identical capacitor such that one plate of uncharged capacitor connected to positive plate and another plate of uncharged capacitor connected to negative plate of the charged capacitor. The loss of energy in this process is measured as $x \times 10^{-2}\,J$. The value of $x$ is $..............$
A resistor '$R$' and $2\ μF$ capacitor in series is connected through a switch to $200\ V$ direct supply. Across the capacitor is a neon bulb that lights up at $120\ V$. Calculate the value of $R$ to make the bulb light up $5\ s$ after the switch has been closed. $(log_{10} 2.5 = 0.4)$.
In Millikan's oil drop experiment an oil drop carrying a charge $Q$ is held stationary by a potential difference $2400\,V$ between the plates. To keep a drop of half the radius stationary the potential difference had to be made $600\,V$. What is the charge on the second drop
Between the plates of a parallel plate condenser, a plate of thickness ${t_1}$ and dielectric constant ${k_1}$ is placed. In the rest of the space, there is another plate of thickness ${t_2}$ and dielectric constant ${k_2}$. The potential difference across the condenser will be
Capacitance of a capacitor made by a thin metal foil is $2\,\mu F$. If the foil is folded with paper of thickness $0.15\,mm$, dielectric constant of paper is $2.5$ and width of paper is $400\,mm$, then length of foil will be.....$m$
