QUESTION:
3. (I) How much kinetic energy will an electron gain (in joules and eV) if it accelerates through a potential difference of 23,000 V in a TV picture tube?
ANSWER:Step 1 of 2
Charge on an electron
Potential difference through which it moves is
Work done in accelerating the electron through the potential difference = kinetic energy gained
Or,
We know that
