New cards

Charging by conduction

when electrons flow from an charged object to an uncharged object

2
New cards

Charging by induction

when a charged rod is brought close to a neutral rod and makes the neutral rod separate its charges

3
New cards

electroscope

device that can be used for detecting charge

4
New cards

elementary charge

the smallest charge observed in nature

5
New cards

Electric charge is said to be

quantized ( existing only in discrete amounts) `

6
New cards

electrostatic force

the force one electrically charged particle exerts on a second one, when they are at rest

7
New cards

electrostatics

charge at rest 

8
New cards

Principle of superposition

the electric force vectors add like any other vector
