An a- particle and a proton are accelerated from rest by a potential difference of 100V. After this, their de-Broglie wavelengths are `lambda_a` and `lambda_p` respectively. The ratio `(lambda_p)/(lambda_a)`, to the nearest integer, is. |

Answer» Correct Answer - A::C `:. lambda =(h)/(p) = (h)/(sqrt2qVm or `lambda prop(1)/(sqrtqm` `(lambda_p)/lambda_a) = sqrt((qa)/(qp). (m_a)/(m_p))` = `sqrt((2)(4))/((1)(1)) =2.828` . The nearest integer is 3. :.Answer is 3. |
