7) Is it possible to have a zero electric field value between a negative and positive charge along the line joining the two charges? ... Yes, regardless of the magnitude of the two charges. C) No, a zero electric field cannot exist between the two charges .
Is it possible for the electric field between two positive charges?
Is it possible for the electric field between two positive charges to equal zero along the line joining the two charges? Yes, regardless of the magnitude of the two charges .
Is electric potential zero when electric field is zero?
Yes, electric potential can be zero at a point even when the electric field is not zero at that point. ... At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.
Where is the electric field the strongest?
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.
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 .
Where is the electric field zero between a positive and negative charge?
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.
Can electric field be negative?
An electric field can never be negative . An electric field is a force experienced by the charge divided by the magnitude of the charge. ... So even if the charge is negative in nature, its magnitude will also be positive and therefore, an electric field can never be negative.
What is the electric field between two equal charges?
At the midpoint of the line joining two equal point charges, the field is zero , and the electric field lines on this line joining the charges each begin at a charge and kind of end at the midpoint.
Why is electric potential constant when electric field is zero?
If the potential is constant, then the slope of the potential is zero , which means the electric field is zero. An extra charge added to an otherwise constant potential region will experience no electrical force. It is an interesting question: Firstly, the Electric field “E” is the slope of the potential, i.e., E=−dVdx.
Where is the electric potential zero?
The electric potential from a single charge is defined to be zero an infinite distance from the charge , and the electric potential associated with two charges is also defined to be zero when the charges are infinitely far apart.
Where is the electric field zero?
To find where the electric field is 0, we take the electric field for each point charge and set them equal to each other , because that’s when they’ll cancel each other out. The ‘s can cancel out. Therefore, the electric field is 0 at .
Where is the field strongest weakest How do you know?
Field-Line Patterns
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. If the lines are uniformly-spaced and parallel, the field is uniform.
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.
Why can’t electric field lines 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.
Is it possible to have a zero electric field value between a negative and negative?
7) Is it possible to have a zero electric field value between a negative and positive charge along the line joining the two charges? ... Yes , regardless of the magnitude of the two charges.
At which point or points is the electric field zero?
The electric field is zero at two points along the x axis ; one such point is to the right of the -2q charge and the other is to the left of the +4q charge. 2.
