A uniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance 5.4 cm. A proton is released from rest at the surface of the positively charged plate. The value of the constant electric field between the plates is 166.8 N/C.

Use:

Mass of a proton= 1.67 × 10-27 kilograms

Charge of a proton = 1.60 × 10-19 C

k = 9 x 109 Nm2 / C2

ε0 = 8.85×10−12 F⋅m−1

1. Calculate the value of the acceleration of the proton then enter the letter corresponding to the correct answer in the box (this entry requires exact match. please enter the letter in lower case and do not enter any spaces, commas or dotts).

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

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

there are no atoms
