The battery A uniform electric field pointing in positive $x$-direction exists in a region. Let $A$ be the origin, $B$ be If on the concentric hollow spheres of radii $r$ and $R(>r)$ the charge $Q$ is distributed such that their surCoulomb's law gives the force between two point charges q₁ and q₂ separated by distance r in vacuum asTwo point charges of +2 μC each are placed 3 m apart in vacuum. The force between them is (k = 9 × 10⁹ N m²/C²The electric field at distance r from an isolated point charge q isThe electric field of an infinite line of charge with linear charge density λ at perpendicular distance r isThe electric field just outside a uniformly charged infinite plane with surface charge density σ isGauss's law states that the total electric flux through a closed surface equalsAn electric dipole consists of two equal and opposite point charges ±q separated by distance 2a. Its dipole moThe electric field on the axial line of a short electric dipole at distance r isAn electric dipole in a uniform electric field E experiencesThe principle of quantisation of electric charge is stated asTwo charges +q and −q of equal magnitude are placed at the corners A and B of an equilateral triangle. The netThe electric flux through a closed surface enclosing a charge of +5 μC is (ε₀ = 8.85 × 10⁻¹² C²/N m²)For a charge distribution with volume density ρ, the total charge Q equalsThe SI unit of electric field isIf a positive point charge is placed at the centre of a spherical conducting shell of radius R (neutral), the Two electrostatic field lines can never:If field lines crossed, the field at that point would lack a unique:Electrostatic field lines never form:Electrostatic field lines are drawn as curves that are:Electrostatic field lines start at charges that are:An electric dipole is a pair of charges that are equal and:The two charges of a dipole are separated by a distance written:The line joining the two dipole charges defines a:By convention, the dipole direction runs from minus q towards:The mid-point between the two dipole charges is called its:The total charge of an electric dipole comes to:Although its total charge is zero, a dipole's field is:The dipole fields fail to cancel because the charges are:Dipole fields are worked out most simply at distances that are:Gauss's law relates the enclosed charge to the electric:In Gauss's law, q stands for the total charge that is:Zero net flux through a closed surface means the charge inside is:Gauss's law holds for a closed surface of:The significance of Gauss's law is that it is true in:Electrostatic field lines end at charges that are:That electrostatic lines do not close follows from the field being:A dipole is described using its two charges and their:
