Practice CBSE Class 12 (Science) Static Electricity in the app →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:
