What is a uniform electric field?
A uniform electric field is a region where the electric field strength is constant in magnitude and direction.
A uniform electric field varies in strength but not in direction.
A uniform electric field is a region with no electric field present.
A uniform electric field has changing direction but constant strength.
How do electric field lines represent the strength of a field?
Electric field lines are always straight and do not indicate strength.
Electric field lines are denser where the field is stronger and sparser where it is weaker.
Electric field lines are stronger when they are further apart.
Electric field lines represent the direction of current flow, not strength.
What is the unit of electric charge?
Watt
Volt
Coulomb
Ohm
What happens when two like charges interact?
Like charges attract each other.
Like charges neutralize each other.
Like charges repel each other.
Like charges create a magnetic field.
What is the effect of a positive charge on a negative charge?
A positive charge repels a negative charge.
A positive charge has no effect on a negative charge.
A positive charge neutralizes a negative charge.
A positive charge attracts a negative charge.
How can you visualize electric field lines?
Use a compass to measure angles
Draw random lines on paper
Observe the color of the sky
Use iron filings or computer simulations to visualize electric field lines.
What is the relationship between electric field intensity and distance?
Electric field intensity increases with distance.
Electric field intensity decreases with the square of the distance from the charge.
Electric field intensity remains constant regardless of distance.
Electric field intensity is directly proportional to the distance from the charge.
What is the role of a test charge in measuring electric fields?
The test charge measures temperature changes in the field.
The test charge is used to store electric energy.
The test charge generates the electric field around it.
The test charge measures the electric field by experiencing a force that indicates the field's direction and magnitude.
How do electric fields affect charged particles?
Electric fields have no effect on charged particles.
Charged particles move randomly regardless of electric fields.
Electric fields cause charged particles to accelerate in the direction of the field for positive charges and opposite for negative charges.
Electric fields only affect neutral particles.
What is the significance of the direction of electric field lines?
The direction of electric field lines indicates the strength of the electric field.
Electric field lines always point towards negative charges regardless of the charge type.
The direction of electric field lines shows the path of current flow in a circuit.
The direction of electric field lines signifies the direction of the electric force on a positive charge.
