The number of field lines that begin or end on a charge is directly proportional to magnitude of charge (2) Electric field lines specify not only the direction of the electric field, but also the direction of the force. This is why the lines are sometimes called lines of force.
What is electric field lines of force?
The electric lines of force represent the field of a positive electric charge in space. It consists of a family of straight lines that radiate uniformly in all directions from where the charge originates. A second positive charge placed in the field that will travel radially away from the first charge.
Is electric field lines and electric lines of force are same?
Note: Electric lines of forces and electric field lines both are the same. These lines start from the positive and end in negative charge. We can relate this concept with magnetic lines of force where field lines originate from the North pole and end in a South pole.
What do the lines of force represent?
Field lines, or lines of force, are used to represent pictorially the electric field . … Field lines point in the direction of the electric field . Field lines cannot cross. If two lines did cross, then the force on a charge would have two directions, which is impossible.
What are electric field lines called?
These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges.
What is electric field formula?
Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q.
What is electric field intensity?
A measure of the force exerted by one charged body on another. Imaginary lines of force or electric field lines originate (by convention) on positive charges and terminate on negative charges.
What are three properties of electric lines of force?
Following are the 3 properties of electric lines of force.
- The electric lines of force start from a positive charge and ends on a negative charge.
- The electric lines of force always enter or leave the charged surface normally.
- Electric lines of force can never intersect each other. Answer verified by Toppr.
What is the SI unit of electric field?
In the metre-kilogram-second and SI systems, the appropriate units are newtons per coulomb, equivalent to volts per metre. In the centimetre-gram-second system, the electric field is expressed in units of dynes per electrostatic unit (esu), equivalent to statvolts per centimetre.
Which is not a property of electric lines of force?
C. Electric field lines do not form any closed loops. The statement is true because the electric field lines start from positive charge and end on negative charge. Since the starting and ending point of the electric field lines is different, a loop can never be closed.
What is the force of a magnet called?
The force that a magnet exerts on certain materials, including other magnets, is called magnetic force. The force is exerted over a distance and includes forces of attraction and repulsion.
What are magnetic lines of force called?
The magnetic lines of force, indicate the region in which the force of the magnet can be detected. This region is called the magnetic field. The magnetic lines of force, or flux, leave the north pole and enter the south pole.
What are the property of magnetic lines of force?
The magnetic lines of force has the following properties:
- Each line is a closed and continuous curve.
- They originate from the north pole and terminate at the south pole.
- They will never intersect each other.
- They are crowded near the poles where the magnetic field is strong.
