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

Two point charges $Q_1$ and $Q_2$ exert a force $F$ on each other when kept certain distance apart. If the charge on each particle is halved and the distance between the two particles is doubled, then the new force between the two particles would be

Find the number of electron that should be removed from a coin so that it acquires a charge of ${10}^{-6}$ coulomb

If a body has positive charge on it, then it means it has

For a proton accelerated through potential difference of one volt, kinetic energy gained in $\mathrm{eV}$ is

Two charges $q$ and $-q$ are placed at $(a, 0)$ and $(-a, 0)$ on the $x-$axis. Another charge $2q$ is taken from $(0, 0)$ to $(0, a)$, then the work done to do so

If a solid and a hollow conducting sphere have same radius then

If two electrons are forced to come closer to each other, the potential energy of the system of $2$ electrons will

When distance between two point charges (one positive and the other negative) is halved, then the electrostatic force between the charges will
