Question: What is the direction of the electric field in the rod?

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

What is the direction of the electric field within the rod?

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.

What is the electric field in the rod?

If the charge present on the rod is positive, the electric field at P would point away from the rod. If the rod is negatively charged, the electric field at P would point towards the rod. In either case, the electric field at P exists only along the x-axis.

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.

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.

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.

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 in the same direction as current?

The current always flows in the same direction as the electric field. The electrons flow in the opposite direction, because they are negatively charged.

What is the charge of A rod?

A long rod bears a charge of λ coulombs per metre of its length.

What are units of electric field?

The units of the electric field in the SI system are newtons per coulomb (N/C), or volts per meter (V/m); in terms of the SI base units they are kg⋅m⋅s3⋅A1.

What is K electrostatics?

The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s2⋅C2.

What is electric field formula?

Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q.

What is the direction of the electric field at the position of this charge?

Its direction is downward. Charged particles attract or repel each other, even when not in contact with each other. We say that charged particles produce electric fields.

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.
