Where do electric field lines point?
The electric field lines are directed away from a positive charge and towards a negative charge so that at any point , the tangent to a field line gives the direction of electric field at that point.
Can electric field intensity be a scalar quantity?
No,because electric field (force/charge) is a vector quantity, i.e. , it has both magnitude as well as direction.
When electric flux is zero then electric field is also zero why?
The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge. Phi= integral E.dA= integral zcDdA = zcQ Phi is zcQ and depends on charge Q, as does E.
What is dimensional formula of coulomb?
The Coulomb is a unit of electric charge. [Charge] is a fundamental quantity.
What is an electric charge less than zero?
Compound
How can one determine the direction of the electric field?
To determine the direction of the electric field, you can use a positive test charge. The direction of the electric field is the direction in which a positive test charge would move if placed in that field.
How can one determine the direction of the electric field at a specific point?
To determine the direction of the electric field at a specific point, you can place a positive test charge at that point and observe the direction in which it experiences a force. The direction of the force on the positive test charge indicates the direction of the electric field at that point.
What determine the direction of flow of charge?
The direction of flow of charge is determined by the electric field present in a circuit. Charge will flow from areas of higher potential energy to lower potential energy, following the direction of the electric field.
What can you determine from an electric field vector at one point?
From an electric field vector at one point, you can determine the direction of the electric field at that point and the strength of the electric field at that point. The electric field vector gives you information about how a positive test charge would be affected at that specific location in the field.
When determining an electric field must a positive test charge be used or would a negative one do as well?
Either a positive or a negative test charge can be used to determine an electric field. The direction of the electric field will be defined by the force experienced by the test charge, with the positive test charge moving in the direction of the field and the negative test charge moving opposite to the field.
Why we use the positive test charge for determining the electric field?
A positive test charge is used to determine the electric field because its direction of motion will be the same as the direction of the electric field. This allows us to measure the electric force experienced by the test charge and therefore calculate the electric field strength at that point.
Is the direction of the electric force on a charge is tangent to the field line?
No, the direction of the electric force on a charge is along the electric field vector and not necessarily tangent to the field line. The force on a charge will be in the same direction as the electric field if the charge is positive, and opposite if the charge is negative.
What is the direction of the electric force on charge a in the figure?
The direction of the electric force on charge a in the figure is towards the right.
If you place a charge into an electric field it will move in the direction indicated by the electric field lines?
Yes, a charge placed in an electric field will experience a force and move in the direction of the electric field lines if it is positive, or opposite to the direction if the charge is negative. The force on the charge is proportional to the charge itself and the strength of the electric field at that location.
What is the purpose of the Millikan oil drop apparatus in determining the elementary electric charge?
The purpose of the Millikan oil drop apparatus is to measure the elementary electric charge, which is the smallest unit of electric charge. This apparatus allows scientists to determine the charge of individual oil droplets by observing their motion in an electric field, helping to accurately calculate the value of the elementary charge.
What is the trajectory of a charge in an electric field?
The trajectory of a charge in an electric field is determined by the direction and strength of the electric field. The charge will experience a force in the direction of the electric field, causing it to move along a path determined by the field's characteristics.
A what will move in the direction of the arrows on the electric field lines?
A positive charge will move in the direction of the arrows on the electric field lines. Electric field lines show the direction a positive test charge would move if placed in the field.
