Answer:
Electric field, [tex]E=9.97\times 10^5\ N/C[/tex]
Explanation:
We have,
Charge on electron is [tex]1.602\times 10^{-19}\ C[/tex]
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 :
[tex]E=\dfrac{kq}{r^2}\\\\E=\dfrac{9\times 10^9\times 1.6\times 10^{-19}}{(38\times 10^{-9})^2}\\\\E=9.97\times 10^5\ N/C[/tex]
So, the electric field inside the picture is [tex]9.97\times 10^5\ N/C[/tex]
Answer:
997,000
