An electron is located on the x axis at x0 = -8.27 × 10-6 m. Find the magnitude and direction of the electric field at x = 1.67 × 10-6 m on the x axis due to this electron. Magnitude:

Respuesta :

Answer:

The magnitude of the electric field at the given point is 14.57 N/C and the direction of the electric field is negative x- direction

Explanation:

Given that,

Electron located on the x axis is [tex]x=-8.27\times10^{-6}\ m[/tex]

Electric field at a point on the x axis is [tex]x'= 1.67\times10^{-6}\ m[/tex]

Magnitude of charge [tex]q=1.6\times10^{-19}\ C[/tex]

We need to calculate the distance between  the electron and the point

[tex]r =  x'-x[/tex]

Put the value into the formula

[tex]r =1.67\times10^{-6}-(-8.27\times10^{-6})[/tex]

[tex]r=1.67\times10^{-6}+8.27\times10^{-6}[/tex]

[tex]r=9.94\times10^{-6}\ m[/tex]

We need to calculate the magnitude of the electric field

Using formula of electric field

[tex]E = \dfrac{kq}{r^2}[/tex]

Put the value into the formula

[tex]E=\dfrac{9\times10^{9}\times1.6\times10^{-19}}{(9.94\times10^{-6})^2}[/tex]

[tex]E=14.57\ N/C[/tex]

The direction of the electric field is negative x- direction because the direction of force on the charge at a given point on the x-axis.

Hence, The magnitude of the electric field at the given point is 14.57 N/C and the direction of the electric field is negative x- direction
