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.
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.
The direction of the electric field vector is defined as?
Direction of the electric field vector is the direction of the force experienced by a charged particle in an external electric field.
What is the electric field around a charged particle like?
The electric field pattern is radial.
Can two electric lines of force intersect each other?
No. If they did, that would mean that at the point of intersection, the force field points in two different directions simultaneously!
Relationship between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -dV/dx, where E is the electric field intensity, V is the electric potential, and x is the distance in the direction of the field. Essentially, the electric field points in the direction of decreasing potential, and the magnitude of the field is related to the rate at which the potential changes.
Is an electric field a potential field?
no electric field is not a potential field .ELECTRIC FIELD IS A SCALAR QUANTITY WHERE AS POTENTIAL IS THE VECTOR QUANTITY. NO SCALAR QUANTITY HAS A FIELD SO THERE IS NO RELATION BETWEEN ELECTRIC FIELD AND POTENTIAL OR IN OTHER WORD POTENTIAL HAS NO FIELD <<>> An electric field is a vector field, because it has magnitude and direction. A pair of charged parallel plates has an electric field between them directed from the negative to the positive plate. The electric field is the gradient of the potential, which is another field but a scalar one. A field is just a quantity with a value that depends on positon. The potential is measured in volts and if one plate is grounded and the other at positive potential V, the potential rises from zero to V as the position changes from the lower plate to the top one.
If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?
Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.
If potential is constant throughout a given region of space can you say that electric field is zero in that region?
If the electric field is zero, the electric potential is a constant value, but it does not tell you what that value is. All the electric field tells you is how the electric potential changes within the region you are looking at. If the electric potential at one end of a cylindrical region is 7 V and the electric field is zero within the whole cylinder, then the electric potential is 7 V at the other end, or somewhere in the middle, or on the side, and so forth. An electric field of zero tells you the potential does not change, but doesn't say anything about what it is outside of the region you're looking at.
In an electric field 0.90 J of work is required to bring 0.45 C of charge from point A to point B. What is the electric potential difference between points A and B?
nn
What is electric potential dependent upon?
The magnitude of the electric potential is dependent upon the particle's charge and the electric field strength.
The electric field inside a hollow uniformly charged sphere is zero Does this imply that the potential is zero inside the sphere Explain?
If the net charge enclosed by a surface is zero then the field at all points on the surface is not zero because gauss's law states that if the charge enclosed by a surface is zero then the flux through the surface is zero which depends upon the magnitude of field and the angle that it makes with the area vector at each point and so it is not necessary that the field will be zero at all points of the surface.
Do electrons move up or down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
Why electric field is negative gradient of electric potential?
This is because potential decreases if we move further from a positive plate
Do electron moves up or fall down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
Is the electric intensity at any two points in a uniform electric field equal?
Yes. That's what "uniform electric field" means.
What happens to electric potential when the electric field is increased?
the electrical potential is also increased;electricity does not travel through wire but around the outside,which is why transmission lines are bare
