Question

Map sapling learning 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 upward. A positive charge within an electric field that points to the right. A negative charge moving out of the screen in a magnetic field that points to the left. charge moving into the screen in a magnetic field that A negative charge moving to the left in an electric field that points into the screen. A positive charge moving downward in a magnetic field that points downward. downward upward out of the screen zero force to the left into the screen to the right

Explanation / Answer

Here ,

magnetic force is given as F = q * V X B

and electric force F = q E

Now ,

A)

for negative charge = electic force is downwards

B)

force is to the right

C)

Here , the force is upwards

D)

Here , the magnetic force is to the left

E)

Here , electric force on negative charge is out of the screen

F)

Here , as both velocity and field are in same direction , magnetic force is ZERO
