What is the effect of increasing the distance between two charges on the electrostatic force?
The electrostatic force decreases, inversely proportional to the square of the distance.
What is the effect of placing a positive charge in an electric field?
The positive charge experiences a force in the direction of the electric field.
What is the effect of placing a negative charge in an electric field?
The negative charge experiences a force opposite to the direction of the electric field.
What happens to the electric field strength as the density of electric field lines increases?
The electric field strength increases.
What is the effect of increasing the magnitude of either charge in Coulomb's Law?
The magnitude of the electrostatic force increases proportionally.
Label the electric field lines around a positive point charge.
Field lines radiate outward from the center of the charge.
Label the electric field lines around a negative point charge.
Field lines radiate inward toward the center of the charge.
Describe the electric field lines between two oppositely charged parallel plates.
The field lines are parallel and equally spaced, going from the positive plate to the negative plate, indicating a uniform electric field.
Describe the electric field lines between two like charges.
The field lines curve away from each charge, and there is a region between the charges where the field is weak.
Compare and contrast test charge 'q' and source charge 'Q'.
Test charge 'q': Used to measure the electric field; its own field is negligible. Source charge 'Q': Creates the electric field.
Compare the electric field strength () due to a point charge and between parallel plates.
Point Charge: varies with distance (). Parallel Plates: is uniform between the plates.
