What are properties of electric lines of force?
Properties of Electric Field Lines
Electric lines of force contract longitudinally. They expand laterally. The magnitude of charge and the number of field lines, both are proportional to each other. The starting point of the field lines is at the positive charge and the ending point is at the negative charge.
What is electric lines of force and its properties Class 12?
An electric line of force is an imaginary curve drawn in such a way that tangent to this curve at any point gives the direction of the electric field at that point. It can be a path with maybe a curve or a straight line.
What do you mean by electric lines of force write four properties?
The properties of electric lines of force are: i) Lines of force start from positive charge and terminate at negative charge. ii) Lines of force never intersect. iii) The tangent to a line of force at any point gives the direction of the electric field at that point.
What are the four properties 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.
What are the property of force?
All forces have two properties: direction and magnitude. A newton (N) is the unit used to describe the magnitude, or size, of a force. What two properties do all forces have? All forces act on objects.
What do you mean by electric field lines Class 12?
An electric field line is an imaginary line or curve drawn from a point of an electric field such that tangent to it (at any point) gives the direction of the electric field at that point.
What are electric field lines give their three important properties?
Properties of Electric Field Lines:
The field lines never intersect each other. The field lines are perpendicular to the surface of the charge. The magnitude of charge and the number of field lines, both are proportional to each other.
What are the properties of field?
Mathematicians call any set of numbers that satisfies the following properties a field : closure, commutativity, associativity, distributivity, identity elements, and inverses.
What are the types of electric field?
There are two types of electric fields: static (or electrostatic) fields and dynamic (or time-varying) fields. Electric fields have a definite magnitude and specific direction.
