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.
Is electric field strength scalar or vector?
The strength of the electric field is a scalar quantity. But it's the magnitude of thecomplete electric field vector.At any point in space, the electric field vector is the strength of the force, and thedirection in which it points, that would be felt by a tiny positive charge located there.
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
Is magnetic field line scalar or vector quantity?
Vector.
