The minimum value of electric feild intensity due to a point charge is 0. The value of electric feild intensity will be 0 at infinity.
Where is the electric field the smallest?
The SPACING of the equipotentials indicates The STRENGTH of the electric field. “This is where the density of the lines is the smallest. “
At what point electric potential is maximum?
In the case of an equipotential surface, the electric field at every point is always normal (to the direction of the electric field (E)). Therefore, the potential at point B is more than C and B. So, the potential at points are VB>VC>VA. Hence, the electric potential at point B is maximum.
At what position field is zero?
In Region II, between the charges, both vectors point in the same direction so there is no possibility of cancelling out. In Region III, the fields again point in opposite directions and there is a point where their magnitudes are the same. It is at this point where the net electric field is zero.
At which point electric field is strongest?
The magnitude of an electric field is directly proportional to the density of electric field lines. When the lines are closer to each other, the >electric field is the strongest; when the filed lines are far apart from each other, the electric field is the weakest.
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.
How electric field is created?
The electric force acts over the distance separating the two objects. … The space surrounding a charged object is affected by the presence of the charge; an electric field is established in that space. A charged object creates an electric field – an alteration of the space or field in the region that surrounds it.
Why does electric potential decrease in electric field?
This is because electric potential is the work done against the direction of electric field.
How do you find the maximum electric potential?
We can use the equation VAB=Ed to calculate the maximum voltage. VAB=Ed. or VAB=75kV. (The answer is quoted to only two digits, since the maximum field strength is approximate.)
Where is the electric field the maximum in a dipole?
It is maximum when p and E point in opposite direc ons, and minimum when they are parallel (note the minus sign).
Can an electric field be zero?
There is no zero-field point for a pair of equal-magnitude-but-opposite-sign charges. Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite. That point is halfway between two like charges.
What happens when electric field is 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.
How do you know if the electric field is 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 .
