Determine the direction of the force if any that will act on

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 to the right. A positive charge within an electric field that points upward. A negative charge moving upward in a magnetic field that points into the screen. A positive charge moving to the right in a magnetic field that points out of the screen. A negative charge moving upward in an electric field that points into the screen. A positive charge moving into the screen in a magnetic field that points into the screen.

Solution

1) The direction of force on electron is towards left

2) the directio of force is upward

3) the force on the neagative charge is to the left perpendicular to the direction of motiona and also magnetic field

4) the force on the postive charge is upward direction perpendicular to the direction of motion and also magnetic field

5)The force on the negative charge points out of the screen

6) No force acts on the charge travelling in the direction of magnetic field.
