Question

Determine the direction of the force (if any) that will act on the charge in each of the following situations. A negative charge within an electric field that points downward. upward A positive charge within an electric field that points to the left. to the left A negative charge moving to the left in a magnetic field that points out of the screen. into the screen A positive charge moving out of the screen in a magnetic field that points downward. to the right A negative charge moving to the left in an electric field that points out of the screen. into the screen A positive charge moving into the screen in a magnetic field that points into the screen. Incorrect. zero force One or more of your answers is not correct. Open the lower panel for more information.

Explanation / Answer

F = qE

1) UPWARD

F = -q*-E = qE

F and E both are in opposite direction

2) LEFT

F = q*-E

F and E both are in same direction

3) downward

F = q(vxB) = -(-ixk) = -j

4) to the right

F = q(vxB) = +( kx -j) = i

5) into the screen

F = -qE

F and both are in opposite direction

6) zero

F = (-kx-k) =0
