Question

If ,  and  are the KE of an , an -particle and a proton, with the same De-Broglie wavelength, then

Canvas Classes · Accepted Answer

Step 1: De Broglie wavelength and KE

For same :

Step 2: Compare masses

| Particle | Mass |
|---|---|
| Electron () |  kg |
| Proton () |  |
| -particle () |  |

Step 3: Order of KE

Since  and :
