Question

Напряженность однородного электрического поля равна 14∙104 Н/Кл. определить расстояние между точками поля, разность потенциалов для которых 2800 В. Ответ выразить в сантиметрах.

Answer 1

Дано U=2800 D   E=14104 Н/Кл
напряженность поля Е=U/d
откуда d=U/E =2800 В /14104 Н/Кл ≈ 0.199 м =19.9  см Ответ 19.9 см

Answer 2

Calculation of Distance and Potential Difference in an Electric Field

To determine the distance between two points in an electric field and the potential difference between them, we need to use the formula relating electric field strength (E), distance (d), and potential difference (V):

E = V / d Given that the electric field strength is 14 x 10^4 N/C and the potential difference is 2800 V, we can rearrange the formula to solve for the distance:

d = V / E

Substituting the given values:

d = 2800 V / (14 x 10^4 N/C)

Calculating this expression will give us the distance in meters. To convert it to centimeters, we can multiply the result by 100 since there are 100 centimeters in a meter.

Let's calculate the distance:

d = (2800 V / (14 x 10^4 N/C)) x 100 cm/m

Calculating this expression, we find that the distance between the two points in the electric field is 20 cm.
