The mass of an electron 1/1840 part of mass of proton. When they are subjected to a uniform elecric field, they start accelerating(b) If they start from rest and have the same de Brogile wavelength of 1Å then determine the ratio of their kinetic energies. |

Answer» SOLUTION :`lambda_e=h/sqrt(2m_ek_e), lambda_p=h/sqrt(2m_pk_p` SINCE these PARTICLES have same WAVELENGTH `h/sqrt(2m_ek_e)=h/sqrt(2m_pk_p )` `m_ek_e=m_pk_p ` ` k_e/k_p=m_P/m_e=1840` |
