The electric field points to the left because the force on a negative charge is opposite to the direction of the field. The electric field points to the right because the force on a negative charge is in the same direction as the field.
Q. What is the direction of the electric field at the dot?

Q. Where are electric fields 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.
Q. Does an electric field go from positive to negative?
Capacitors and Electric Fields The electric field points from the positive to the negative plate- left to right. The electric field points in the direction of the force that would be on a positive charge. An electron will move in the opposite direction of the electric field because of its negative charge.
Q. How do you find the distance in an electric field?
the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.
Q. Can electric field lines cross each other?
Field lines can never cross. Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would imply that the electric field was pointing in two different directions at a single point.
Q. Why do electric field lines not cross each other?
Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible.
Q. Why do electric field lines start on positive?
The electric field due to a positive charge extends radially out in all directions from the charge (because a positive test charge placed near it would feel a force pointing away from it). In general, electric field lines always point from positive charges and toward negative charges. …
Q. What is the electric field due to an infinite wire?
As the electric field E is radial in direction, flux through the end of the cylindrical surface will be zero, as electric field and area vector are perpendicular to each other. The only flowing electric flux will be through the curved Gaussian surface.
Q. What shape Gaussian surface should we use in order to find the electric field due to an infinite uniformly charged sheet?
cylindrical Gaussian
Q. How do you calculate total enclosed charges?
QT, the total charge enclosed, = q coulombs per meter x L meters. = QT = D x 2pr x L . Gauss’ electrostatics law is also written as a volume integral: This equation states that the charge enclosed in a volume is equal to the volume charge density, r, (rho) summed for the entire volume.
