Consider the provided figure which shows two charged particles at a certain distance from each other. In what point between the two charged particles will the electric field be zero?

• At a point near the charge on the left

• At a point near the charge on the right

• At the midpoint between the two particles

• There is no point where the electric field is zero.

What is the SI unit of potential difference?

• Volts

• Newtons

• Joules

• Coulombs

What is the term used to describe a sometimes imaginary surface that encloses a region in space?

• Carl surface

• Gaussian surface

• Gauss surface

• Friedrich surface

The electric potential at a point where a test charge is is V. What happens to the electric potential at that point when the magnitude of the test charge is doubled?

• It becomes 2V.

• It becomes V/2.

• It remains the same.

• The distance from the source charge should be known first.

What law is used to calculate the electric force acting on a charged particle?

• Ohm's law

• Newton's law

• Gauss's law

• Coulomb's law

Electric force is to electric field as electric potential energy is to what?

• Electric field

• Electric potential

A negatively-charged particle is placed in a region where the electric field is uniformly directed upward. What force does the particle experience?

• Upward

• Downward

• Leftward

• Rightward

Two objects, A and B, are rubbed vigorously together. Using a tool, it was found out that B became positively-charged. Which statement BEST explains the phenomenon?

• Protons are transferred from A to B.

• Electrons are transferred from A to B.

• Protons are transferred from B to A.

• Electrons are transferred from B to A.

Which statement correctly describes an equipotential surface?

I. It is perpendicular to the electric field.

II. The work done on a charged particle is zero when its path is along this surface.

• Both I and II

• I only

• II only

• Neither I nor II
