Question

Яка напруженість електричного поля на відстані 1 см від точкового заряду 0,1 мКл?

Answer 1

q=0.1 мКл =0.1*10^-3 Кл.

L=1 см =0.01 м

k=9*10^9 Н·м2/Кл2 - постоянная Кулона

----------------

Е - ? напряженность

 

общая формула для расчета напряженности

Е=kq/L^2 =9*10^9*0.1*10^-3 /0.01^2=    9*10^9 В/м

 

Ответ   9*10^9 В/м

Answer 2

Electric Field Intensity at a Distance from a Point Charge

The electric field intensity at a distance from a point charge can be calculated using Coulomb's law. Coulomb's law states that the electric field intensity, E, at a distance, r, from a point charge, q, is given by the equation:

E = k * (q / r^2)

Where: - E is the electric field intensity - k is the electrostatic constant (k = 9 x 10^9 Nm^2/C^2) - q is the charge of the point charge - r is the distance from the point charge

In this case, we have a point charge of 0.1 mC (0.1 x 10^-3 C) and a distance of 1 cm (0.01 m). Plugging these values into the equation, we can calculate the electric field intensity.

E = (9 x 10^9 Nm^2/C^2) * (0.1 x 10^-3 C) / (0.01 m)^2

Calculating this expression gives us the electric field intensity at a distance of 1 cm from the point charge.
