Note: +q = positive charge and –q =
negative chargeQ:What would the lines of force look like around two negative particles?
A:They would look like the lines around two positive particles, except the arrows would point toward, rather than
away from, the negative particles.
Summary
- An electric field is a space surrounding a charged particle where the particle exerts electric force.
- When charged particles are close enough to exert force on each other, their electric fields interact. Particles
with opposite charges attract each other. Particles with like charges repel each other.
Vocabulary
- electric field: Space around a charged particle where the particle exerts electric force on other particles.
