Determine the direction of the force (if any) that will act on the charge in each of the following situations. a positive charge within an electric field that points to the right. negative charge within an electric field that points downward. a positive charge moving downward in a magnetic field that points out of the screen. a negative charge moving to the right in a magnetic field that points into the screen. a positive charge moving upward in an electric field that points into the screen. a negative charge moving to the right in a magnetic field that points to the right. to the right to the left into the screen zero force downward out of the screen upward

a) F on the right , b)    F up , c) Force to the left , d)  Force down , e)  Force towards the screen , f) Force is zero

Explanation:

The equations for the forces are

Electric

          F = q E

Magnetic

          F = q v x B

The Bold are vectors, the charges are positive

Let's apply these equation to the proposed situations

a) as the load is positive the force goes in the direction of the field

      F on the right

b) as the load is negative the force goes in the opposite direction to the field

     F is up

c) positive charge with speed down and magnetic field out of the screen.

For this part we will use the right hand rule. The thumb is in the direction of the speed, the fingers extended in the direction of the magnetic field and the palm is in the direction of the force for a positive charge

       Force to the left

d) negative charge, speed to the right magnetic field between the screen

   The force has direction

      Force down

e) positive charge, electric field towards the screen.

     Force in the direction of the field

        Force towards the screen

.f) negative charge, speed to the right, magnetic field to the right

    The vector product is zero,

     Force is zero

answer: strength i guess
