A stationary shell of mass '5m' explodes in to two parts and their masses are in the ratio 2:3, then the ratio of their de-Broglie wavelengths associated with the above two parts respectively is 1) 2:3 The ratio of the de Broglie wavelength of proton, deuteron and alpha particle when 14. 2) 3:2 3) 9:4 4) 1:1 15. accelerated through the same potential difference 100V is 1) 2:2:1 2) 1:2:2 2 3) 2:1:2 4) 2/2:2:1
