A particle is moving three times as fast as anelectron. The ratio of the de Broglie wavelength of the particle to that of the electron is 1.813 xx 10^(-4). The mass of the particle is (Mass of electron = 9.1xx10^(-31) kg ) |

Answer» `1.67xx10^(-27)` kg `lambda=h/p=h/(mv)` or `m=h/(lambdav)` Given : `v/v_e=3, lambda/lambda_e=1.813xx10^(-4)` Mass of the particle , `m=m_e(v_e/v)(lambda_e/lambda)` Substituting the VALUES , we GET `m=(9.1xx10^(-31) kg) xx (1/3) xx(1/(1.813xx10^(-4)))` `RARR m=1.67xx10^(-27)` kg |
