Electric Fields

Question 1

A source charge generates an electric field of 1236 N/C at a distance of 4 m. What is the magnitude of the source charge? (Use k=)

Revolt · Accepted Answer

2.2 µC

Question 2

An electric field is represented by the force on which particle?

Revolt · Accepted Answer

a positive test charge

Question 3

The diagram shows a charge moving into an electric field.

Revolt · Accepted Answer

Y

Question 4

A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw based on this description?

Revolt · Accepted Answer

The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

Question 5

Liana draws a diagram to show the direction of the electric force acting on a charged particle in a uniform electric field.

Revolt · Accepted Answer

changing the force to point right

Question 6

A pair of opposite electric charges of equal magnitude is called a(n)

Revolt · Accepted Answer

dipole.

Question 7

What is the direction of the electric field at a point directly below a negative charge, Q?

Revolt · Accepted Answer

up

Question 8

What is the direction of the electric field at a point directly to the left of a positive charge, Q?

Revolt · Accepted Answer

left

Question 9

Which best describes the electric field created by a positive charge?

Revolt · Accepted Answer

Its rays point away from the charge.

Question 10

The strength of the electric field 0.5 m from a 6 µC charge is _______ N/C. (Use k = 8.99 × 109 N• and round answer to the nearest whole number.)

Revolt · Accepted Answer

215760
