Embibe Experts Solutions for Exercise 1: EXERCISE 1.1

Two charged particles $\mathrm{q}$ and $4\mathrm{q}$ are kept at distance $3 \mathrm{m}$ as shown in figure,

The force on a charge $\mathrm{Q}$ kept at $\mathrm{P}$ is

There are two charged particles of same nature, and they are fixed. The position of equilibrium for a third charge will be

Three charged particles each having a charge $\mathrm{q}$ are kept fixed at the vertices of an equilateral triangle of side length $\mathrm{L}$. The net electrostatic force on any one of the charged particles is

If five identical charged particles of charge ' $q$ ' each are kept at vertices of regular hexagon, then force acting on a charge '$- q$ ' kept at centre of hexagon is (Here, $r$ is distance of vertex from, centre of hexagon)

Two charges $Q_1$ and $Q_2$ are separated by a distance $D$. If both $Q_1$ and$D$ are doubled, the force is

Two charges $Q_1$ and $Q_2$  are separated by a distance $D$. If $Q_1,Q_2$ and$D$ are all doubled, the force is
