How are the field lines related to the intensity of an electric field?
an electric charge seas up an electric field in it's surroundings.it exerts force upon any charges which arrives in this field region.the force will be stronger when the field intensity is higher
Can two electric field lines be drawn at a point?
No, if two electric field lines are drawn at a point, this would meant two directions of electric field at that point which is impossible.
Why electric field lines cannot have sudden brakes in between them?
electric field lines represents electric field at that point but if it has break somewhere then it signifies the absence of electric field and it is not possible.....
Two point charges plus q and -q are held some distance apart what are the points at which the resultant field is parallel to the line joining the two charges?
The system of two point charges plus q and -q constitutes an electric dipole.In the case of an electric dipole ,the resultant field is parallel to the line joining the two charges at 1.any point on the line joining the charges 2.any point on the perpendicular bisector of the line joining the two charges.
What is the unit for intensity?
The unit of intensity is decibels (dB). mw/cm2

What do you mean by electric flux in electrostatics?
Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force. Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.
Can two electric field lines be drawn at a point?
No, if two electric field lines are drawn at a point, this would meant two directions of electric field at that point which is impossible.
Where do electric field lines point?
The electric field lines are directed away from a positive charge and towards a negative charge so that at any point , the tangent to a field line gives the direction of electric field at that point.
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
What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
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

Can electric field lines intersect in free space?
No, because the electric field would not be defined at the intersection point.
How do you calculate Electric field due to an isolated point charge point charge?
yes it can We have Epsilon equals charge by area imagine a photographic enlargement of the charge inside which this point charge exists then you can calculate B(Mag. Field intensity) We have E=Int.(B.dA) Was ur doubt clarified?
What is the unit for intensity?
The unit of intensity is decibels (dB). mw/cm2
