1. a pair of oppositely charged parallel plates is separated by 5.51 mm. a potential difference of 614 v exists between the plates. what is the strength of the electric field between the plates? the fundamental charge is 1.602 × 10? 19 . answer in units of v/m.
2. what is the magnitude of the force on an electron between the plates? answer in units of n.
3. how much work must be done on the electron to move it to the negative plate if it is initially positioned 2.7 mm from the positive plate? answer in units of j.

Part a)

Part 2)

Part 3)

Explanation:

Part 1)

As we know that electric field and potential difference related to each other as

so we will have

so we have

Part 2)

Charge of an electron

now force is given as

Part 3)

Work done to move the electron

i believe your answer is d mgf2

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
