Determine the direction of the force (If any) that will act on the charge in each of the following situations.

A. A positive charge within an electric field that points downward
B. a negative harge within an electric field that points to the left
C. a positive charge moving out of the screen in a magneti field that points to the right
D. a negative charge moving downward in a magnetic field that points into the screen
E. a positive charge moving to the right in an electric field that points into the screen
F. a positive charge moving out of the screen in a magnetic field that points out of the screen

The options are: to the left, out of the screen, downward, into the screen, upward, to the right, zero force

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
