Study Notes
Electric Charge and Electric Field
- Electric charge is the source of electric field, and every charged particle produces an electric field around itself.
- Like charges (two positive or two negative) repel each other, while opposite charges (one positive and one negative) attract each other.
Electric Field Interaction
- An electric field exerts a force on other charged particles, causing them to accelerate or decelerate.
- The direction of the force depends on the charge of the particle and the direction of the electric field.
- Positive charges accelerate in the direction of the electric field, while negative charges accelerate in the opposite direction.
Electric Field Strength
- The strength of an electric field around a point charge decreases as the distance from the charge increases.
- The electric field strength is inversely proportional to the square of the distance from the point charge.
- At very large distances, the electric field strength becomes negligible.
