What is the quantity of an electric field?
The electric is a vector quantity. We know that electric field is the ratio of force per unit test charge. Since, force is a vector quantity, electric field is also a vector quantity.
What are the different units of electric field?
Electricity and Magnetism
| Physical Quantity | Unit |
|---|---|
| Electric Field | [Newtons / Coulomb] |
| epsilon0 | [Coulomb2 / meter2 / Newton] |
| Electric Flux | [Coulomb meter2] |
| Electric Potential | [Volts] = [Joules / Coulomb] |
What are 4 properties of electric fields?
Properties of an Electric Field
- Field lines never intersect each other.
- They are perpendicular to the surface charge.
- The field is strong when the lines are close together, and it is weak when the field lines move apart from each other.
- The number of field lines is directly proportional to the magnitude of the charge.
What is E KQ R 2?
The formula E=kQr2 is the electric field of a point charge in radial direction at a distance r from the charge. This means, especially, that the field is not homogeneous, i.e. not the same at every point in space.
Is electric field a scalar quantity or vector quantity?
As mentioned earlier, electric field strength is a vector quantity. Unlike a scalar quantity, a vector quantity is not fully described unless there is a direction associated with it.
Why is electric field a vector quantity?
Secondly, the electric field has a direction that is outward from positive charges and inward to negative charges. To be concluded, the electric field has both magnitude and direction which are the standards to be defined as a vector quantity. Hence, an electric field is a vector quantity.
What is the unit and dimension of electric field?
Or, E = [M1 L1 T-2] × [I1 T1]-1 = [M1 L1 T-3 I-1]. Therefore, the Electric Field is dimensionally represented as [M1 L1 I-1 T-3].
Is electric field a physical quantity?
Electric field lines represent the flow of a physical quantity. Electric field lines represent the flow of a physical quantity.
What is electric field 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.
What is k in V kQ R?
the electric potential (V) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation: V = kQ/r, where k is a constant with a value of 8.99 x 109 N m2/.
