Ohm's Law

Question 1

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 2

Which statements about electric field lines are correct? Check all that apply.They point toward a positive charge.They point toward a negative charge.They point away from a positive charge.They point away from a negative charge.They cross over one another between charges.They never cross.

Revolt · Accepted Answer

They point toward a negative charge.; They point away from a positive charge.; They never cross.

Question 3

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 4

An electric field around two charged objects is shown.

Revolt · Accepted Answer

X: positiveY: negative

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

Revolt · Accepted Answer

215760

Question 7

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 8
