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

Explanation / Answer

Here,

A) as electric force = electric field * charge

as charge is negative

the electric force will point to the right

B)

electric force = electric field * charge

the direction of electric force will be in the direction of field

electric force will be upwards

C)

as F = q * V X B

as the charge is negative

the direction of magnetic force will be towards left

D)

for the force

F = q * V X B

the diretion of magnetic force will be downwards

E)

as electric force = electric field * charge

as charge is negative

the electric force will point out of the screen

F)

as the magnetic field and direction of motion of charge on the anti parallel

the force acting on the positive charge is Zero
