Two identical pendulums $A$ and $B$ are suspended from the same point. Both are given a positive charge, with $A$ having more charge than $B$. They diverge and reach equilibrium with the strings of pendulums $A$ and $B$ making angles $θ_{1}$ and $θ_{2}$ with the vertical respectively. Then:

An electron moves with a velocity $v$ in an electric field $E$. If the angle between $v$ and $E$ is neither 0 nor $π$, then the path followed by the electron is a(an):

A charge $Q$ is divided into two parts $q_{1}$ and $q_{2}$ such that they experience maximum force of repulsion when separated by certain distance. The ratio of $Q,q_{1}$ and $q_{2}$ is :
