Question

Determine the direction of the force (if any) that will act on the charge in each of the following situations.

Choices: To the left, Upward, To the right, Out of the screen, Into the screen, Zero force, Downward

1. A positive charge within an electric field that points downward.

2. A negative charge within an electric field that points to the right.

3. A positive charge moving to the right in a magnetic field that points into the screen.

4. A negative charge moving downward in a magnetic field that points out of the screen.

5. A positive charge moving to the left in an electric field that points out of the screen.

6. A positive charge moving to the right in a magnetic field that points to the left.

Here ,

electric force is given as Fe = q * E

and magnetic force is given as Fm = q*(V X B )

we use fleming's left hand rule to find the direction of magnetic force

1. A positive charge within an electric field that points downward.

force is downwards

2. A negative charge within an electric field that points to the right.

force is to the left

3. A positive charge moving to the right in a magnetic field that points into the screen.

force is upwards

4. A negative charge moving downward in a magnetic field that points out of the screen.

force is to the right

5. A positive charge moving to the left in an electric field that points out of the screen.

force is out of the screen

6. A positive charge moving to the right in a magnetic field that points to the left.

the force is ZERO
