What type of charge does an electron carry?
Positive
Neutral
Negative
Both positive and negative
Which of the following is an example of charging by friction?
Charging a balloon by rubbing it on hair
Touching a charged object to a neutral one
Bringing a charged rod near a neutral object
Grounding an object
What happens during a thunderstorm?
Only strong winds blow
Water vapor freezes
Electric charges build up and discharge
Clouds move silently
When a charged object is brought near a neutral object without touching it, and the neutral object gets charged, it is called:
Friction
Conduction
Induction
Radiation
What is the charge on a neutron in an atom?
Positive
Negative
Zero
Depends on the atom
Charging by conduction involves:
Rubbing two objects
Bringing objects close without touching
Direct contact between a charged and uncharged object
Flow of heat
A positively charged object has more protons than electrons.
Lightning is an example of a large-scale electric discharge.
Charging by conduction does not require contact between objects.
Induction can charge an object without touching it.
Rubbing a plastic comb on dry hair can transfer electrons.
Which particles are transferred during the process of charging by friction?
Protons
Electrons
Neutrons
Atoms
What does a lightning conductor do?
Attracts rain clouds
Prevents lightning
Directs lightning safely to the ground
Stores electric charge
What is the main cause of lightning?
Water in clouds
Accumulation and discharge of electric charge in clouds
High-speed winds
Moon’s gravity
Which of the following is an example of charging by conduction?
A charged rod touches a neutral metal sphere
A balloon sticks to a wall without touching it
Combing hair with a plastic comb
Lightning striking a tree
What kind of materials allow electric charges to move freely through them?
Insulators
Plastic
Conductors
Rubber
When an object is positively charged, it has:
Gained electrons
Lost electrons
Gained protons
Lost protons
In a thunderstorm, which part of the cloud is usually negatively charged?
Lower part
Upper part
Middle part
Entire cloud is neutral
What is an electroscope used for?
To measure sound waves
To detect earthquakes
To detect the presence of electric charge
To record thunder sounds
Why should we not stand under a tree during a thunderstorm?
Trees attract wind
Trees fall during storms
Trees can attract lightning and conduct electricity to the ground
Trees block rain
What happens to a plastic rod when rubbed with wool?
It loses electrons
It gains electrons and becomes negatively charged
It becomes positively charged
Nothing happens
