GENERAL PHYSICS REVIEW

What is the value of the electric field, in N/C, exactly in the midway between two equally positive particles?

• 0

• 1

• 3

• 2

Which area is positively charged?

• A

• B

• C

• D

Given the electric field, in which direction would the electron go into?

• A

• B

• C

• D

Electric lines of force about negative point charge are?

• Circular, anticlockwise

• Circular, clockwise

• Radial, outward

• Radial, inward

The electric field lines passing through a surface area are called:

• Electric Flux

• Electric Field

• Electric Charge

• Electric Lines

A positive test charge placed near a negative charge would have________ potential energy.

• zero

• high

• low

• one

The electric flux Φ through a surface

• is the electric field multiplied by the area.

• is the amount of electric field piercing the surface

• does not depend on the area involved

• is the line integral of the electric field around the edge of the surface

A charge is sitting outside a closed surface. The net flux is

• double because it passes through two surfaces

• zero because it passes through two surfaces

• squared because it passes through two surfaces

• half because it passes through two surfaces

What does a radial direction of an electric field signify?

• The magnitude of the electric field throughout all the points of the spherical Gaussian surface is inversely proportional to the linear charge density.

• The magnitude of the electric field is undeterminable throughout all the points of the spherical Gaussian surface.

• The magnitude of the electric field throughout all the points of the spherical Gaussian surface is directly proportional to the area

• The magnitude of the electric field is equal throughout all the points of the spherical Gaussian surface.

Define potential difference

• The amount of energy per charge

• The amount of charge per second

• The amount of charge per energy

• The amount of voltage per second
