Electric Fields, Flux and Potential

What is the unit of electric field?

• N/C (Newton per Coulomb)
• C/N (Coulomb per Newton)
• V/m (Volt per meter)
• J/C (Joule per Coulomb)

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.

Which of the following charges has electric field lines pointing outward?

• Positive charge
• Negative charge
• Neutral charge
• No charge

What force does a charge experience in an electric field?

• Electric force (F)
• Gravitational force (F)
• Magnetic force (F)
• No force

In which direction do electric field lines point around a negative charge?

• Toward the charge
• Away from the charge
• Perpendicular to the charge
• They form a circle

What is the relationship between force and electric field?

• F = qE
• F = q/E
• F = E/q
• F = q/E²

What is the electric field created by a single positive charge?

• Radially outward
• Radially inward
• Circular
• Tangential

What happens to the electric field strength as you move closer to a charge?

• It increases
• It decreases
• It remains constant
• It becomes zero

What is the electric field magnitude for a force of 0.060 N acting on a -2.0 x 10^-8 C charge?

• 3 x 10^6 N/C
