Why is an electric field strength a vector quantity?
for a vector quantity it must have both magnitude and direction and since it has both magnitude and direction it is therefore considered a vector
Can electric field intensity be a scalar quantity?
No,because electric field (force/charge) is a vector quantity, i.e. , it has both magnitude as well as direction.
What are the vector and scalar fields?
In mathematics, a field is a set with certain operators (such as addition and multiplication) defined on it and where the members of the set have certain properties. In a vector field, each member of this set has a value AND a direction associated with it. In a scalar field, there is only vaue but no direction.
Why is the electric field considered a vector quantity?
Because to completely describe it you must know both how strong it is (magnitude) and in what direction it points.
What physical quantity use both magnitude and direction?
Any vector quantity does. Examples of vector quantities include but are not limited to . . . - Displacement - Velocity - Acceleration - Torque - Force - Electric field - Momentum - Poynting vector
Why is an electric field considered a vector quanity?
Because if you place a small object with a small electric charge in the field and release it, there's a definite direction in which it will move under the influence of the field. The direction in which a positive test-charge tries to move is defined as the direction of the electric field at that point. Since it has both a magnitude and a direction, it has all the qualifications to be recognized as a vector, and to be granted all the rights and privileges attendant thereto.

What is the relationship between the electric magnetic and wave velocity vectors?
The wave velocity vector is parallel to the cross product of the electric and magnetic vectors.If you crank a wood screw from the Electric-field direction to the Magnetic-field direction, the screw proceedsinto the wood in the direction of the wave's velocity vector.Here's another advanced and highly technical way to keep these directions straight ...Curl the fingers of your right hand in the direction FROM the electric vector TO the magnetic vector.Your right thumb (when extended) points in the direction of the waves velocity vector, and alsothe "Poynting Vector"; that's the direction in which the wave carries energy.
What are principal planes in antenna wave propagation?
The principal plane in wave propagation is the E-plane and the H-plane of an antenna. The E-plane consists of the electric field vector, and by convention, it's the direction in which the wave is said to be 'polarized'. The H-plane consists of magnetic field vector of the wave. The electric field vector and the magnetic field vector are perpendicular to each other, and the direction in which the wave propagates (moves) is perpendicular to both of them.
What are two exambles of vector quantities?
A vector quantity is any measurement where the direction is relevant, such as position, velocity, acceleration, force, electric field, etc.
Why is the electric field is a vector?
Because to completely describe it you must know both how strong it is (magnitude) and in what direction it points.
What is the difference between gradient and vector notation?
In the name of God; It must be mentioned that a vector has two important characteristics; 1- direction and 2- quantity. in other word for identification a vector these two characteristics must be defined. for example when we speak about displacement of a body it must has direction and quantity. but about gradient, it has a general mean: difference. Also a specified mean may be defined for it: "any increase or decrease in a vector or scalar field". it is a vector field.
What is the Difference between plane of polarization and plane of vibration?
A plane including the direction of light propagation and the direction of electric field is called the "plane of vibration". The "plane of polarization" is a confinement of the electric/magnetic field vector to a given plane along the direction of propagation.
What is electric field vector in plane polarised light?
This is the electric field vector of a plane-wave light beam of angular frequency ω=2πc/λ travelling in the direction of a unit vector n with velocity c: E=E(0) exp [-iω(t-n·r/c)]
What will be the effect on the motion of electron if it travels along the dirction of electric field?
The "direction" of the electric field is defined as the direction of the force it exerts on a small positive charge. The direction of the force on an electron in the field is exactly opposite to the direction of the field, and its effect is to accelerate the electron in the direction of the force.
