Embibe Experts Solutions for Chapter: Electrostatics, Exercise 1: Exercise

Two identical particles of mass $1\mathrm{\mu g}$ And charge $100\mathrm{\mu C}$ Are kept $1 \mathrm{m}$ apart. Will they repel or attract each other;

Point charges $1 \mathrm{\mu C}$ and $6 \mathrm{\mu C}$ are placed in air at a certain distance apart. The magnitude of the force on $1 \mathrm{\mu C}$ by $6 \mathrm{\mu C}$ is ${\mathrm{F}}_1$. The magnitude of the force on $6 \mathrm{\mu C}$ by $1 \mathrm{\mu C}$ is ${\mathrm{F}}_2$. Then ${\mathrm{F}}_1:{\mathrm{F}}_2$ is:

At certain distance from a point charge electric field and potential are $50 \mathrm{V}/\mathrm{m}$ and $300 \mathrm{V}$ respectively, this distance is

The electric field at a point outside the plates of two oppositely charged plane sheets of charge density $\text{'}\mathrm{\sigma }\text{'}$ is:

An electric dipole has the magnitude of its charge as $q$ and its dipole moment is $p$. It is placed in a uniform electric field $E$. If its dipole moment is along the direction of the field, the force on it and its potential energy are respectively

An electric dipole has the magnitude of its charge as $q$ and its dipole moment is $p$. It is placed in a uniform electric field $E$. If its dipole moment is along the direction of the field, the force on it and its potential energy are respectively

A capacitor stores $50\mathrm{ }\mathrm{\mu }\mathrm{C}$ charge when connected across a battery. When the gap between the plates is filled with a dielectric, a charge of $150\mathrm{ }\mathrm{\mu }\mathrm{C}$ flows through the battery. The dielectric constant of the material is:

If voltage applied on a capacitor is increased from $\mathrm{V}$ to $2 \mathrm{V}$, choose the correct conclusion.
