Away from the charge
What is the SI unit of electric charge?
Coulomb
Which material allows electric charges to move freely?
Conductor
What is the relationship between electric field strength and distance from a point charge?
Electric field strength is inversely proportional to the square of the distance from the point charge
In which direction does an electron move in an electric field?
Opposite to the direction of the electric field

Study Notes
Electric Field and Charge
- The direction of the electric field due to a positive charge is radially outward from the charge.
- The SI unit of electric charge is the coulomb (C).
Conductors
- A conductor is a material that allows electric charges to move freely.
Electric Field Strength
- The electric field strength decreases with an increase in distance from a point charge, following the inverse square law.
Electron Movement
- An electron moves in the opposite direction of the electric field, i.e., it moves from a region of higher potential to a region of lower potential.
Electric Potential Energy
- When two like charges are brought closer together, their electric potential energy increases.
