Q. Four particles given, have same momentum. Which has maximum kinetic energy
A) Proton
B) Electron
C) Deutron
D) $\alpha$- particles
Explanation
(b) $E = \frac{P^{2}}{2m}\ \therefore E \propto \frac{1}{m}$ [If $P =$ constant]
$i.e$., the lightest particle will possess maximum kinetic energy and in the given option mass of electron is minimum
