What is continuous electric field?
Electric field due to a continuous charge distribution – example. Example: A rod of length l with uniform charge per unit length λ is placed at a distance d from origin along the x-axis. A similar rod is placed at the same distance along Y-axis.
What does an electric field tell you?
What is an electric field, and what does it tell you? A vector function of position indicating the strength and direction of the electric force on a charged object. … They are useful for describing the effect of any non-contact force.
Why is electric field continuous?
Yes, the electrostatic field line is a continuous curve because a unit charge always experiences a continuous force when it is placed in an electrostatic field. The unit charge is the charge that passes through the cross-section of an electric conductor that carries one ampere of current in one second.
Is the electric field always continuous?
Roughly speaking, yes, it’s always continuous in an electrostatic field. However, the electric potential at the point where the electric field source(charge) occupies is not defined.
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 scalar?
No, electric field is not a scalar. The electric is a vector quantity. … Since, force is a vector quantity, electric field is also a vector quantity.
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 If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
What is the relationship between electric force and electric field?
The strength of the electric field is defined as the electrostatic force experienced by a small test charge qo placed at that point divided by the charge itself. The electric field is a vector, and its direction is the same as the direction of the force on a positive test charge.
