At which point is the electric field strongest quizlet?
A. Vector is down and to the left. The electric field is strongest at A since it is closest to the charge.
What is the direction of the electric field at a point directly to the left of a positive charge q?
The direction of electric field is determined by the magnitude of electric charge i.e either the charge is positive or negative. So, the direction of electric field at a point directly to the left of a positive charge, Q is towards left.
What is the direction of the electric field at a point that is directly to the left of a negative electric charge?
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.
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 If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
When electric field lines get closer together what does that tell you about the electric field?
17. When electric field lines get closer together, what does that tell you about the electric field? The electric field is inversely proportional to the density of electric field lines. The electric field is directly proportional to the density of electric field lines.
Which best describes electric field created by a positive charge?
The direction of the electric field of a positive charge is away from the charge. The direction of the electric field of a negative charge is towards the charge. Therefore, the electric field created by a positive charge describes its rays point towards the charge.
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 electric field a vector?
Electric field strength is a vector quantity; it has both magnitude and direction.
