For a standard, uniform charge distribution, the electric field is perpendicular to the ring and follows , giving us no electric field at the center of the ring, where z=0.
What is the electric field in the center of the ring?
So the field at the center of the ring is zero.
What is the direction of the electric field at the center of the circle?
As electric field points away from positive charge and toward negative charge, at the center of the ring The field is in the −x direction.
How do you find the direction of an electric field?
The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. Since electric field is a vector quantity, it can be represented by a vector arrow.
Why is electric field at centre of Ring zero?
What is the magnitude of the electric field at the center of a ring of charge of radius a? Assume there is a charge Q uniformly distributed over the ring. The field from one side of the ring cancels the field from the other, so the net field at the center is zero.
Why electric field lines do not have sudden breaks?
An electrostatic field line is a continuous curve because a charge experiences a continuous force when placed in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump fom one point to another.
What is the direction of the electric field of a positive charge?
Electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field. Thus, the electric field direction about a positive source charge is always directed away from the positive source.
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.
Which best describes the 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.
What is the direction of the field?
Explanation: Electric field is electric force per unit charge. And the direction of the field is the direction of the electric force it would exert on a positive test charge.
Does electric field have direction?
Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.
What are the strength and direction of the electric field?
The direction of the electric field due to positive point charge is always acts away from the point charge and electric field due to the negative charge acts towards the negative charge. The electric field is a vector quantity. They cannot be added directly, but can be added vectorially.
