Question

Inside a television picture tube there is a build-up of electrons (charge of 1.602 × 10–19 C) with an average spacing of 38.0 nanometers between electrons. Find the electric field inside the picture tube. (Round to three significant figures.)

Answer 1

997,000

Step-by-step explanation:

just did the assignment for electric fields, grade 10. have a nice day :)

Answer 2

Electric field,
`E=9.97* 10^5\ N/C`

Step-by-step explanation:

We have,

Charge on electron is
`1.602* 10^(-19)\ C`

Distance between electron is 38 nm.

It is required to find the electric field inside the picture tube. The electric field at a distance r is given by :

`E=(kq)/(r^2)\\\\E=(9* 10^9* 1.6* 10^(-19))/((38* 10^(-9))^2)\\\\E=9.97* 10^5\ N/C`

So, the electric field inside the picture is
`9.97* 10^5\ N/C`
