Which of the following are not properties of lines of force in electric field?
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 not a property of electric field lines?
Field lines are always normal to conducting surface and they do not form closed loops. Field lines may have break, they do not exist inside a conductor.
Which of the following are the properties of lines of force in an electric field?
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. The start point of the field lines is at the positive charge and end at the negative charge.
What is the direction of electric lines of force?
The electric lines of force that represent the field of a positive electric charge in space consist of a family of straight lines radiating uniformly in all directions from the charge where they originate. A second positive charge placed in the field would travel radially away from the first charge.
What is SI unit of electric flux?
Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C−1).
Which of the following is a property of a uniform electric field?
Electric field lines never intersect. In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.
Can electric lines of force pass through a conductor?
Therefore, the electric field lines do not pass through a conductor. …
What are electric lines of force what is its importance?
What is its importance? An electric line of force is an imaginary straight or curved path along which a small positive test charge is supposed to move when free to do so. The tangent at a point on an electric line of force gives the direction of the resultant electric field at that point.
What do electric lines of force represent?
Electric lines of force are drawn to point out the direction of electric field. They originate from positive charge and terminate at negative charge. … Electric lines of force represents the direction of electric field.
What is electric field lines and its properties?
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. Properties : 1. Electric field lines starting from positive charge and terminating at a negative charge.
