Which of the following is not a characteristic of electric field lines?

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 electric field lines and its properties Class 12?

An electric field line is a curve drawn in such a way that the tangent to it at each point is in direction of the net field at that point. Electric field is inversely proportional to the square of the distance; hence electric field near the charge is high and keeps on decreasing as we go farther from the charge.

What is electric field lines in physics?

An electric field line is an imaginary line drawn in such a way that its direction at any point is the same as the direction of the field at that point. Field–line in general is a curve drawn in such a way that the tangent to it at each point in the direction of the net field at that point.

Why do the electric field lines?

Electric field lines provide a means to visualize the electric field. Since the electric field is a vector, electric field lines have arrows showing the direction of the electric field. As two examples, we show the electric field lines of a single point charge, and of a positive and negative charge.

How do you know if an electric field is uniform?

The force on the charge is the same no matter where the charge is located between the plates. This is because the electric field is uniform between the plates.

Can electric field be negative?

An electric field can never be negative. An electric field is a force experienced by the charge divided by the magnitude of the charge.

What is uniform electric field explain with diagram?

A uniform electric field is one whose magnitude and direction is same at all points in space and it will exert same force of a charge regardless of the position of charge in space. It is represented by parallel and evenly spaced lines. For example we find uniform electric field between parallel plates of a capacitor.

How can we produce a uniform electric field?

The simplest method of creating a uniform electric field in a region is to keep two equally charged thin plain metal sheets of opposite charge parallel to each other.

What is the uniform electric field?

A uniform electric field is a field in which the value of the field strength remains the same at all points. In a uniform electric field, as the field strength does not change and the field lines tend to be parallel and equidistant to each other. They are equally spaced.

What is the relation between electric field and potential difference?

The relationship between potential and field (E) is a differential: electric field is the gradient of potential (V) in the x direction. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.

Which of the following is uniform electric field?

Answer: c) Two parallel plates.

What is uniform and nonuniform electric field?

If an electric field has the same magnitude and same direction everywhere in a given space then this electric field is uniform, and if either the magnitude or direction or both change then it is a non-uniform electric field in that specified space.

What direction is electric field?

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

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.
