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:

Six charges are placed at the corner of a regular hexagon as shown. If an electron is placed at the centre O, force on it will be:

$4$ charges are placed each at a distance 'a' from origin. The dipole moment of configuration is :

$A$ and $B$ are two points on the axis and the perpendicular bisector respectively of a electric dipole. $A$ and $B$ are far away from the dipole and at equal distance from it. The field at $A$ and $B$ are :

An electric dipole is placed in a uniform electric field. The net electric force on the dipole

Two large parallel planes charged uniformly with surface charge densities $σ$ and $−σ$ are located as shown in the figure. Which one of the following graphs shows the variation of electric field along a line perpendicular to the planes as one moves from A to B?

When a negative charge is released and moves in electric field, it moves toward a position of :

A closed surface in the shape of a cube is placed in a uniform electric field $E$ along one of the sides of the cube as shown here. The length of the side is $l$. The total electric flux through two faces 1 and 2 is:

If the electric flux entering and leaving an enclosed surface respectively are $ϕ_{1}$ and $ϕ_{2}$ the electric charge inside the surface will be:

A cylinder of radius R and length L is placed in the uniform electric field E parallel to the cylinder axis. The total flux from the curved surface of the cylinder is given by :
