Equipotential lines in a constant electric field are always parallel in nature. A field line is created tangentially to the net at a point. why the electric field lines are continuous? The electric field lines describe the magnitude of electric charge by the length of the electric field lines and show the maximum intensity of electric charge by coming closer to each other. Reason: Because if the cross each other then at the intersection point there will be two tangents in two different directions, which will represents the two different directions of electric field, which is wrong. Example 2: Calculate the strength of the electric field at a distance of 12 cm with a voltage of 68 V. Example 3: A force of 12 N is acting on the charge of 27 C. The field lines provide lateral loads or pressure to one another. Hence the electric field has greater strength near the charges. What is the significance of electric field lines? There are many properties of these lines. CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. The field lines are perpendicular to the surface of the charge. These field lines never intersect each other. As such, the field lines never intersect each other. The closeness of field lines indicates the relative strength of the electric field at that point. Electric field lines move away from the positive electric charge and towards the negative electric charge. Except near the edges, the excess charges distribute themselves uniformly, producing field lines that are uniformly spaced (hence uniform in strength) and perpendicular to the surfaces (hence . Also, we can have some idea of the strength of electrostatic force by observing the number of electric field lines present there. Electric field line start from positive charge +qAnd it end on negative change - q.Electric field is strong where field lines are close and it is weak where. Equipotential lines are always in a perpendicular direction to the electric field. It can not be seen and is purely an imaginary concept. According to Faraday, electric field lines give a visual representation of the electric field. The magnitude of charge and the number of field lines, both are proportional to each other. The non-uniform electric field is one that is irregular at every point. An electric field can be represented by imaginary lines of force. E-field is a term used to describe the electric field. The field lines never intersect each other. Field lines are continuous lines. Therefore, the field lines never intersect each other. Properties of Electric field Lines 1. 1 below. hey point in the direction in which the acceleration of the positive test charge would happen if placed upon the electric field line. Electric field lines never intersect each other. This occurs when different charges carrying particles attract each other. Few images depict the electric field lines of point charges and two charges of the different and same polarity. The electric field line always originates from the positive charge and terminates on the negative charge. Properties of electric field lines: There are no field lines beginning or ending in the space around a charge. We became to know that the charges of the same sign will go away and opposite charges will come closer due to electrostatic interactions. This occurs when different charges carrying particles attract each other. An electric field or electrostatic field refers to the region around an electric charge in which the action of electric force takes place. N/C (Newton/Coulomb) is the SI unit for an electric field. 2. This happens on a spot that is along the line t Access free live classes and tests on the app. Ans. Consequently, bending a part of the electric field lines happens when charges carrying particles repel each other. The field is stronger if the field lines are nearer together. The magnitude of the electric field is represented by electric field lines. They can extend up to an infinite distance from the charge. The electric field was represented by the electric field line in the diagram. What are the properties of electric field lines? Some general properties of these lines are as follows: Electric field lines start from a positive charge and end at a negative charge, in case of a single charge, electric field lines end at infinity They also ensure that the potential difference between them at every point turns out to be the same. If we join the different positions of the charge during its motion, we will get a line. Get answers to the most common queries related to the NEET UG Examination Preparation. The number of field lines is directly proportional to the magnitude of the charge. Also, the magnitude of charge and the number of field lines are proportional to each other. Therefore, in such a situation, one can observe the two directions of the electric field at a single point. The electric field lines converge in case of negative charge and diverge in .
