What phenomenon is observed when we feel a shock when touching someone?

• Static electricity

• Electromagnetism

• Electric current

What is surface tension?

• The pressure exerted by a liquid due to its depth.

• The cohesive force at the surface of a liquid that makes it behave like a stretched elastic sheet.

• The tendency of fluids to flow in parallel layers without mixing.

• The resistance of a fluid to flow.

Who discovered that amber attracts dust and leaves?

• Aristotle

What are valence electrons?

• Electrons in the nucleus

• Electrons in the outer shell

• Electrons in the center of the atom

What is capillarity?

• The property that causes small objects to float on water without sinking.

• The resistance of a fluid to deformation or shear.

• The pressure a fluid exerts due to its depth.

• The tendency of a liquid to rise or fall in a narrow tube due to adhesive and cohesive forces

What instrument is used to detect electric charge?

• Electroscope

• Multimeter

• Ammeter

What law did Charles Coulomb formulate?

• Law of gravitation

• Coulomb's law

• Ohm's law

What is Coulomb's law?

• The electric force between two charged objects is directly proportional to the product of the amount of charge on the objects and inversely proportional to the square of the distance between the two objects.

• The electric force between two charged objects is inversely proportional to the product of the amount of charge on the objects and directly proportional to the square of the distance between the two objects.

• The electric force between two charged objects is equal to the sum of the charges of the objects.

• The electric force between two charged objects is equal to the difference of the charges of the objects.

What does the direction of an electric field indicate?

• The direction of the force on a positive test charge.

• The direction of the force on a negative test charge.

• The direction of the force on any charge.

• The direction of the force on a neutral charge.
