The field is strongest
where the lines are most closely spaced
. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.
Where is the electric field zero?
There is a spot along the line connecting the charges,
just to the “far” side of the positive charge (on the side away from the negative charge)
where the electric field is zero. In general, the zero field point for opposite sign charges will be on the “outside” of the smaller magnitude charge.
Which point has the largest magnitude of electric field?
ii)
Charge C
has the largest magnitude as it has the greatest number of electric field lines coming out.
In what region is the electric field strongest?
The direction of the field line at a point is the direction of the field at that point. The relative magnitude of the electric field is proportional to the density of the field lines.
Where the field lines are close together the field
is strongest; where the field lines are far apart the field is weakest.
Where is the electric field the smallest?
b) The electric field is the smallest
on the horizontal line through the middle charge
, at two positions on either side where the field lines are least dense.
Can an electric field be zero?
For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges. For opposite charges of equal magnitude,
there will not be any zero electric fields
.
Can electric field be negative?
Electric field is not negative
. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
Which charge has largest magnitude?
From the given figure it is clear that, maximum number of electric lines of force are associated with
charge C
, so it must have the largest magnitude.
Is electric field conservative in nature?
The work done to carry a test charge (q) from point A to another point B in the field due to Q does not depend upon the path followed. Electric field depends upon the initial and final positions A and B. Electric fields are independent of the path followed. So we say that
the electric field is conservative in nature
.
Which charge has the largest magnitude justify?
(b) As maximum number of electric lines of force are associated with
charge C
, it must have the largest magnitude. (c ) There cannot be a neutral point between a positive and a negative charge. Neutral point can be there only between two like charges, ie., A and C.
Why can electric fields never cross?
Electric field lines cannot cross. … This is because they are, by definition,
a line of constant potential
. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
What are the three rules for drawing electric field lines?
- 1) Electric field lines are always drawn from High potential to. …
- 2) Two electric field lines can never intersect each other.
- 3) The net electric field inside a Conductor is Zero.
- 4) Electric field line from a positive charge is drawn radially outwards and from a negative charge radially inwards.
At which point is the electric field weakest?
Electric field strength is greatest where the lines are closest together and weakest
where lines are furthest apart
.
Are electric field lines straight?
In an uniform electric field,
the field lines are straight, parallel and uniformly spaced
. The electric field lines can never form closed loops, as line can never start and end on the same charge. … Also, this is the path on which a positive test charge will tend to move if free to do so.
What is Q in electric field?
The symbol q in the equation is the
quantity of charge on the test charge
(not the source charge). … Electric field is the force per quantity of charge on the test charge. The electric field strength is not dependent upon the quantity of charge on the test charge.
How do you know the direction of an electric field?
For example, if you
place a positive test charge in an electric field and the charge moves to the right
, you know the direction of the electric field in that region points to the right.
