Q.
The kinetic energy of an electron, which is accelerated in the potential difference of $100$ volts, is
AIPMTAIPMT 1997Dual Nature of Radiation and Matter
Solution:
Potential difference $(V)=100$ volts.
Kinetic energy of an electron (K.E.)
$=e V=\left(1.6 \times 10^{-19}\right) \times 100$
$=1.6 \times 10^{-17}$ joule
