Static Electricity and Coulomb's Law Quiz

What happens to a balloon when it is rubbed against a sweater?

• It loses protons and becomes negatively charged.

• It loses electrons and becomes positively charged.

• It gains protons and becomes positively charged.

• It gains electrons and becomes negatively charged.

Which of the following is NOT a method of charging an object?

• Friction

• Radiation

• Contact

• Induction

What is the role of grounding in static electricity?

• It attracts protons to the object.

• It prevents electrons from moving.

• It provides a path for electrons to spread out into the Earth.

• It increases the charge on an object.

How does induction differ from contact charging?

• Induction requires direct contact between objects.

• Induction involves the transfer of protons.

• Induction causes charge redistribution without direct contact.

• Induction only occurs in metals.

What happens to the electrons in a wall when a negatively charged balloon is brought near?

• They are attracted to the balloon.

• They remain stationary.

• They redistribute away from the balloon.

• They move closer to the balloon.

What is the interaction between two objects with opposite charges?

• They both become neutral.

• They attract each other.

• They have no interaction.

• They repel each other.

According to Coulomb's Law, what happens to the force between two charges if the distance between them is doubled?

• The force doubles.

• The force is halved.

• The force is quartered.

• The force remains the same.

What is the unit of charge used in Coulomb's Law?

• Coulomb

• Meter

• Joule

• Newton

What is the effect of increasing the charge on one of two interacting objects?

• The force becomes zero.

• The force remains unchanged.

• The force decreases.

• The force increases.

What is Coulomb's constant approximately equal to?

• 8.99 x 10^9 N m²/C²

• 9.81 m/s²

• 6.63 x 10^-34 J s

• 1.60 x 10^-19 C
