Let be the point’s location. The radius for the first charge would be , and the radius for the second would be . Therefore, the only point where the electric field is zero is at , or 1.34m.
At which point is the electric field zero in C?
The electric field is zero somewhere on the x axis to the left of the +4q charge. C) The electric field is zero somewhere on the x axis to the right of the 2q charge.
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.
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.
Is it possible to have a zero electric field value?
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.
Why electric field inside a conductor is zero?
Electric field is zero inside a charged conductor. For a charged conductor, the charges will lie on the surface of the conductor.So, there will not be any charges inside the conductor. When there is no charge there will not be electric field.
What is the direction of the electric field at the position indicated by the dot in the figure?
The direction of the electric field is radially outward for positive charges and radially inward for negative charges.
Which of the following describes the electric field produced by the positive charge?
Which of the following describes the electric field produced by the positive charge? The electric field is directed radially away from the charge at all locations near the charge. … You will see the magnitude of the electric field given in units of V/m (volts per meter, which is the same as newtons per coulomb).
Can electric field be zero when electric potential is not 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.
What does it mean if electric potential is zero?
What zero potential means, roughly, is that the charges in your system have cancelled out. For example exactly half way (or otherwise equidistant from them) between two equal and oppositely charged point charges, potential is zero.
