Question

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

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 upward in a magnetic field that points downward.

Explanation / Answer

force on + chareg is in the diection of electric field, for -ve in the opposite direction

force on +ve chareg in teh direction of v cross B in magnetic field, for -ve in teh direction of B cross v, force on stationary chareg and in which v is parallel to B is zero

1)downwards

2)left

3)upwards

4)left

5)out of the screen

6)zero
