142435 A proton and an $\alpha$-particle are accelerated from rest to the same energy. The de-Broglie wavelength $\lambda_{p}$ and $\lambda_{\alpha}$ are in the ratio

142437 The ratio of de Broglie wavelengths of molecules of Hydrogen and Helium in two different gas jars at temperatures of $127^{\circ} \mathrm{C}$ and $227^{\circ} \mathrm{C}$ respectively is

142438 A particle performs uniform circular motion with an angular momentum $L$. If the frequency of particle's motion is doubled and its kinetic energy is halved, then the angular momentum becomes

142439 A proton and an electron initially at rest are accelerated by the same potential difference. Assuming that a proton is 2000 times heavier than an electron, what will be the relation between the de Broglie wavelength of the proton $\left(\lambda_{p}\right)$ and that of electron $\left(\lambda_{e}\right)$ ?
