Electrons are accelerated in the picture tube of a television through potential difference of 8.00 * 10 ^ 3 V. (Use the values q e =1.60*10^ -19 kg and m e =9.109*10^ -31 kg.) Please please hel?

Explanation:

Give that,

The potential difference of the electrons,

We need to find the wavelength of the electrons.

Using the conservation of energy,

Put all the values,

So, the wavelength of the electrons is .

i think it would be 5
