Class 12PhysicsDual Nature of Radiation and matterDavisson-Germer Experiment and Heisenberg Uncertainty Principle
DifficultConsider two separate ideal gases of electrons and protons having the same number of particles. The temperature of both gases is the same. The ratio of the uncertainty in determining the position of an electron to that of a proton is proportional to :-
- A$\left(\frac{m_{p}}{m_{e}}\right)^{3/2}$
- B$\sqrt{\frac{m_{e}}{m_{p}}}$
- C$\sqrt{\frac{m_{p}}{m_{e}}}$
- D$\frac{m_{p}}{m_{e}}$
